FREQUENTLY ASKED QUESTIONS

Why does my hair deteriorate during the day and at night? What really damages it?

Your hair deteriorates during the day because it is exposed to constant damage. The sun produces UV rays that oxidize the hair fiber. This oxidation creates oxidative stress that damages the protein structure. Your hair becomes dull, dry, and brittle. Air pollution contains fine particles that settle on your hair. These particles create an opaque layer that prevents light from reflecting. Your hair looks dull. These particles also create oxidative stress that damages the fiber. The heat of the day also exacerbates the damage. If you use a hair dryer or flat iron, the heat damages the protein bonds that maintain the fiber's structure. Your hair becomes fragile and brittle. Alternating humidity and dryness also create stress. When the air is humid, water penetrates the fiber and causes it to swell. When the air is dry, the water escapes. These constant changes create mechanical stress that damages the fiber. Your hair also deteriorates during the night. While you sleep, your scalp sweats. This sweat, mixed with sebum, creates a warm, humid environment. This environment promotes inflammation and the proliferation of bad bacteria. Inflammation damages the hair fiber. Bad bacteria produce toxins that oxidize the fiber. You go to bed with wet or damp hair. Water creates mechanical stress on the fiber. Protein bonds are damaged. You toss and turn while you sleep. Rubbing against the pillow creates mechanical stress. Hair breaks. You need protection during the day and regeneration during the night. A day serum creates a protective barrier against UV rays, pollution, and heat. A night serum soothes inflammation and regenerates the fiber while you sleep. Together, they create complete 24-hour protection. After a few applications, you will notice that your hair is shinier and stronger. After 2 to 3 weeks, damage will visibly slow down. After 4 weeks, your hair will be noticeably healthier and more resistant. This is the effect of progressive protection and regeneration.

How does day/night protection really work? Why is it different from a traditional serum?

A classic serum simply moisturizes. A day/night serum offers complete protection and regeneration. It's a completely different approach. The day serum creates a protective barrier against external aggressions. Antioxidants (vitamin E, polyphenols) neutralize free radicals created by UV rays and pollution. Without antioxidants, free radicals damage the fiber. With antioxidants, the fiber is protected. Natural UV filters (chamomile extract, green tea extract) create a barrier against UV rays. UV rays oxidize the fiber. With a UV barrier, the fiber is protected. Silicones also create a protective barrier. But silicones build up and create an opaque layer. This day serum does not contain silicones. Instead, it contains a light essential wax that creates a barrier without build-up. Organic hydrosols provide light nourishment. Damask rose soothes. Chamomile protects. Orange blossom creates shine. Together, they create a light and effective protective barrier. The day serum must also be light. You apply it in the morning to damp hair. It must not weigh it down. Cationic hyaluronic acid moisturizes without weighing it down. It penetrates the fiber instead of remaining on the surface. Your hair is moisturized and light. The night serum provides complete regeneration. During the night, your body regenerates. So does your scalp. The night serum provides the ingredients necessary for this regeneration. Probiotics gradually colonize your scalp during the night. They restore the natural balance of the flora. A balanced flora means less inflammation and better regeneration. Postbiotics reduce inflammation immediately. Over 8 hours, they gradually reduce inflammation. Your scalp calms down. The hair fiber regenerates better. Regenerating extracts (ginseng extract, licorice extract) stimulate cell regeneration. During the night, when your body regenerates, these extracts amplify this process. Your hair fiber regenerates more quickly. Ceramides restore the damaged lipid barrier. During the day, the barrier is damaged by UV rays and pollution. During the night, ceramides restore it. A restored barrier means better hydration and better protection. Cationic hyaluronic acid deeply hydrates during the night. While you sleep, hyaluronic acid penetrates the fiber and rehydrates it. Your hair wakes up hydrated. The combined day and night action creates 24-hour protection and regeneration. During the day, you protect against damage. At night, you regenerate. Together, they create a progressively stronger and healthier fiber. A classic serum does not contain these specific ingredients. It simply moisturizes. This day/night system treats all aspects of hair health 24 hours a day. That's why the results are so different. After a few weeks, you'll notice that your hair is shinier and stronger. After 4 weeks, the transformation is visible. Your hair is noticeably healthier and more resistant.

My hair is very damaged/colored/frizzy. Can these serums really help me, or is it too late?

Yes, these serums can significantly reduce damage even for very damaged hair. But it's important to understand what serums can and cannot do. Serums cannot completely repair split ends. You have to cut them off. But serums stop the progression of damage and strengthen healthy hair. For severely damaged hair, these serums offer essential protection and regeneration. Severely damaged hair has a severely damaged lipid barrier. Water escapes quickly. External aggressions penetrate easily. The day serum creates a protective barrier that prevents water from escaping. The night serum provides ceramides that restore the lipid barrier. Together, they stop the progression of damage. The antioxidants in the day serum neutralize free radicals that create oxidative stress. Less oxidative stress means less damage. The regenerating extracts in the night serum stimulate cell regeneration. Your hair fiber regenerates more quickly. After a few weeks, very damaged hair appears less brittle. After 4 to 6 weeks, the progression of damage is stopped. After 8 weeks, your hair is noticeably stronger. For colored hair, these serums offer essential color protection. Colored hair is structurally more fragile. Coloring opens the cuticle to deposit pigment. This opening weakens the fiber. The day serum protects color by creating a barrier against UV rays. UV rays oxidize color pigments. With a UV barrier, your color lasts longer. The antioxidants in the day serum neutralize the free radicals that oxidize pigments. Your color stays more vibrant. The night serum restores the lipid barrier damaged by coloring. A restored barrier means better pigment retention. Your color lasts longer and stays more vibrant. After a few weeks, you'll notice that your color lasts longer. After 4 weeks, your color is visibly more vibrant. For very frizzy hair, these serums offer protection against humidity. Frizzy hair puffs up in humid conditions. The day serum creates a barrier against humidity. The essential wax seals the fiber and prevents water from penetrating. Your frizz is reduced. The antioxidants in the day serum also reduce oxidative stress, which aggravates frizz. The night serum restores the lipid barrier. A restored barrier means less puffiness in humid conditions. Your frizz gradually decreases. After a few weeks, you will notice a visible reduction in frizz. After 4 weeks, your hair will be noticeably less frizzy. Important to know: These serums cannot repair split ends. You have to cut them off. But they stop further damage and strengthen healthy hair. After 4 to 6 weeks, you will see a real improvement. Your hair will be stronger, shinier, and healthier.

How should I apply these serums? When and how many drops? Can I use them with other products?

Proper application is crucial for achieving the best results. The day serum should be applied in the morning after shampooing and conditioning. Apply to damp or slightly damp hair. Water slightly opens the cuticle and promotes penetration. Apply 2 to 5 drops depending on your hair type. For fine hair, use 2 to 3 drops. For thick hair, use 4 to 5 drops. For very long hair, use 5 to 6 drops. Warm the drops slightly between your palms. This helps with penetration. Distribute evenly over the lengths and ends. Focus on the most damaged areas. No rinsing. You can style your hair immediately afterwards. The day serum should remain on your hair all day to provide continuous protection. Dosage according to hair type: Fine hair: 2 to 3 drops. Thick hair: 4 to 5 drops. Very long hair: 5 to 6 drops. Very short hair: 1 to 2 drops. Colored hair: 3 to 4 drops (extra protection). Frizzy hair: 4 to 5 drops (extra barrier). The night serum is applied in the evening before bed. Apply to dry scalp. Apply 1 to 2 mL directly to the scalp, section by section. Use a fine-tipped applicator for precise application. Massage gently with your fingertips for 1 to 2 minutes. Massaging promotes penetration and circulation. Leave on overnight without rinsing. Probiotics, postbiotics, and regenerating extracts work while you sleep. Dosage according to hair type: Fine hair: 0.5 to 1 mL. Thick hair: 1 to 1.5 mL. Very long hair: 1.5 to 2 mL. Very short hair: 0.5 mL. Very irritated scalp: 1 to 2 mL (additional regeneration). Recommended frequency: Day serum: daily. Night serum: daily. Compatibility with other products: You can use these serums with any shampoo and mask. They complement your existing routine without changing it. They are an addition, not a replacement. For maximum effectiveness, use them with the shampoo and mask from the complete routine. Together, they create a complete synergy. You can also use the day serum with other styling products. Apply the day serum first, then the other products. The order is important. Practical tip: Start with a small amount and gradually increase as needed. Every head of hair is different. You will quickly find the ideal amount. The important thing is to distribute it evenly and let it work. After a few applications, you will master the technique and see visible results.

How long before I see a real difference? When will I see my hair repair itself and become shiny?

The results of the day and night serums are visible gradually. You won't see an instant transformation, but the results are visible and long-lasting. Day 1: From the very first application, your hair immediately feels softer and more supple. This is the immediate effect of hydration and the protective barrier. But this effect is temporary. After a few hours, the effect diminishes slightly. This is normal. The fiber has not yet been restored. Days 2 to 7: After a week of daily use, you will notice that your hair stays softer and more supple for longer. The effect now lasts 24 hours. You will also notice that your hair is slightly shinier. This is the effect of the protective barrier, which reflects light better. Weeks 2 to 3: After two to three weeks, the improvement becomes visible. Your hair is noticeably softer, more supple, and shinier. The lipid barrier begins to restore itself. Hydration lasts longer. You also notice that your hair is less brittle. Week 4: After four weeks, the repair is significant. Your hair is visibly stronger, shinier, and healthier. The lipid barrier is gradually restored. Moisture now lasts 48 hours or more after application. You also notice that your hair is less frizzy (if you had this problem). Weeks 5 to 8: After 4 to 6 weeks, repair is complete. Your hair is noticeably stronger and healthier. The lipid barrier is restored. Hydration now lasts 48 to 72 hours. You also notice that your hair is growing back stronger and healthier. This is the effect of the gradual regeneration of the scalp. After 8 weeks: After 8 weeks, your hair is transformed. It is soft, supple, shiny, and strong. The lipid barrier is restored. Hydration is long-lasting. You may notice a visible increase in density and strength. Results are maintained with regular use. Timeline for colored hair: Weeks 1 to 2: Your color appears slightly more vibrant. This is the effect of the protective barrier. Weeks 3 to 4: Your color is visibly more vibrant. You also notice that your color lasts longer. After 8 weeks: Your color lasts significantly longer and remains more vibrant. Timeline for frizzy hair: Week 1 to 2: Your frizz is slightly reduced. This is the effect of the moisture barrier. Week 3 to 4: Your frizz is reduced by 30 to 50%. You will notice a real difference. After 8 weeks: Your frizz will have decreased by 50 to 80%. Your hair will be noticeably less frizzy. Important to know: The timeline depends on the initial condition of your hair. If your hair is very damaged, the timeline may be longer (8 to 12 weeks). If your hair is moderately damaged, the timeline is shorter (4 to 6 weeks). Listen to your hair. After 2 to 3 weeks, you will see a real improvement. After 4 weeks, the transformation is visible. After 8 weeks, your hair is noticeably healthier.

Why are these serums better than a traditional serum? Why not just use a simple oil or protective spray?

A classic serum simply moisturizes. An oil creates a barrier but weighs down the skin. A protective spray offers light protection but not enough moisture. These day and night serums offer a comprehensive approach: protection, hydration, and regeneration. A classic serum contains 60 to 80% inert water. This day serum contains 0% added water. Instead, it contains 100% active organic hydrosols. Inert water does nothing. It dilutes the active ingredients. You pay for volume, not performance. Organic hydrosols contain aromatic molecules, minerals, and antioxidants. These molecules penetrate the fiber and remain there. They provide real protection and nutrition. Oil creates a protective barrier. But oils build up and create an opaque layer. Your hair becomes heavy and greasy. This day serum creates a barrier without build-up. Light essential wax creates a protective barrier without weighing hair down. Your hair remains light and shiny. A protective spray offers light protection. But it doesn't contain enough antioxidants for real protection. This day serum contains powerful antioxidants (vitamin E, polyphenols) that truly neutralize free radicals. Your hair fiber is truly protected. A classic serum does not contain probiotics or postbiotics. This night serum is rich in them. Probiotics rebalance the skin flora. Postbiotics regenerate immediately. A classic serum cannot do this. That's why the results are so different. An oil does not contain probiotics or postbiotics. It just creates a barrier. This night serum offers complete regeneration. Probiotics, postbiotics, and regenerating extracts create an optimal environment for regeneration. A classic serum does not contain enough ceramides. This night serum is rich in them. Ceramides restore the damaged lipid barrier. Without ceramides, the barrier cannot rebuild itself. An oil does not contain ceramides. It just creates a temporary barrier. This night serum truly restores the barrier. A classic serum often contains silicones that build up. This day serum does not contain silicones. Instead, it contains a light essential wax that does not build up. Your hair remains light and healthy. Oil also often contains silicones. This day serum offers real protection without silicones. 98% natural ingredients, free from sulfates, parabens, and silicones. Traditional serums often contain harsh ingredients. These serums respect your hair while protecting and regenerating it. A traditional serum costs $15-25 and lasts 1 month. These serums cost more but last 2 to 3 months and offer 3 times better results. The cost per use is comparable, but the effectiveness is much higher. An oil costs €10-20 and lasts 2 months. But it weighs hair down and creates build-up. These serums offer better protection without weighing hair down. A protective spray costs €8-15 and lasts 1 month. But it offers light protection and not enough hydration. These serums offer complete protection plus deep hydration. After one use, you will feel the difference. Your hair is immediately softer and shinier. After 2 to 3 weeks, the transformation is visible. After 4 weeks, your hair is noticeably stronger, shinier, and healthier. That's why these day and night serums are superior to traditional serums, oils, and protective sprays.
