INGREDIENTS
  • Capixyl 5%™: combines a biomimetic peptide and red clover extract rich in biochanin A, acting as a powerful DHT inhibitor to slow hair loss while strengthening and revitalizing follicles.

  • Baicapil 4%™: combination of three plants (scutellaria, soy and wheat) which stimulate growth, improve hair density and restore vitality and thickness to weakened hair.

  • Redensyl 3%™: promotes the regeneration of hair follicle stem cells, stimulates the hair growth phase (anagen) and significantly reduces hair loss.

Can the Anti-Hair Loss Serum No.1 be used during pregnancy or breastfeeding?

As a precaution, we recommend consulting a healthcare professional before using the Anti-Hair Loss Serum No.1. Its formula is 100% natural, hormone- and drug-free. However, it is advisable to show the full list of ingredients to your doctor or midwife, as the product has not been tested on pregnant or breastfeeding women.

Are there any contraindications?

No known major contraindications. However, our formula contains a small amount of alcohol, used to promote the penetration of active ingredients. This may not be suitable for sensitive or irritated scalps. If discomfort or irritation occurs, discontinue use and consult a healthcare professional.

How long after application can I wash my hair?

The Anti-Hair Loss Serum No.1 does not make the hair greasy. We recommend leaving it on for several hours, ideally overnight, to allow the active ingredients to fully penetrate the scalp and work in depth.
Since it doesn’t leave any oily residue, there’s no need to wash your hair every morning, it’s entirely up to your preference.

Can the Anti-Hair Loss Serum No.1 cause hair growth on other parts of the body?

The Anti-Hair Loss Serum No.1 only stimulates hair growth on the scalp. It has no effect on hair on other parts of the body.
