Keratin: beauty and treatments

Keratine is the structural protein that makes up hair, nails, and the outer layers of the skin. When it decreases — due to heat, chemical agents, or simply the passage of time — the fiber loses compactness, shine, and strength. This collection features over 600 selected products for those who want to reintegrate, protect, and enhance keratin with an informed and conscious approach.

How to choose the right keratin product for you

The first criterion is to understand in what form you want to act. Topical treatments — shampoos, masks, serums, conditioners — work on the surface of the hair or nail, smoothing and protecting the existing structure. Dietary supplements with hydrolyzed keratin support well-being from the inside: in this case, always check the label and, if in doubt, consult your doctor or pharmacist. A common mistake is to layer multiple intensive treatments at the same time: oversaturation can weigh down the hair instead of strengthening it. Choose a single rich leave-in treatment and pair it with at most one rinse-out treatment per week.

The second criterion concerns the concentration and format of keratin. Hydrolyzed keratin has smaller molecules and penetrates the shaft better than non-hydrolyzed keratin, which remains on the surface with a coating effect. For very damaged or chemically treated hair, prefer formulas with high molecular weight hydrolyzed keratin combined with humectants. For brittle nails, look for specific products in hardening or nourishing formulas. Also consider the format: single-dose vials are ideal for periodic intensive treatments, while standard format products are better suited for daily routines.

Frequently Asked Questions

Is keratin suitable for all hair types?

In most cases, yes, but fine hair tends to get weighed down more easily. In that case, prefer lightweight or spray formulas, avoiding ultra-rich masks for frequent use.

Do keratin-based supplements really work?

Supplements can contribute to the normal maintenance of hair and nails if used as directed on the label. To assess suitability for your specific case, the advice of a doctor or pharmacist remains the most reliable reference.

How often should I use intensive keratin treatments?

Once or twice a week is generally sufficient for rinse-out treatments. Leave-in treatments are applied at every wash, on lengths dried with a hairdryer, without exceeding the amount.
