How to revitalize hair?

Stress, seasonal changes, weight-loss diets and exposure to cold and pollution all affect the health of your hair. Apart from conditioners, which treat the exterior without taking into account the source of the problem, many active ingredients can help you regain a glossy mane.

• Colloidal silica is known to stimulate hair growth and improve hair quality. It is found in nettles and alfalfa and as a phytotherapy supplement.
• Vitamin B : Vitamins B6 and B3 aid keratin synthesis. Vitamins B2 and B8 reinforce the resistance and elasticity of keratin. Vitamin B5 encourages hair growth by stimulating the hair follicles.
• Cystine and methionine : these two amino acids are the main constituents of keratin and, therefore, of hair.
• Zinc, iron and silicon are involved in the synthesis of cystine and methionine.
