COUVRé Protein Hair Expander

(1 review)
Instantly make your hair appear thicker and fuller with the COUVRé Protein Hair Expander. The absorption of this product’s organic proteins thicken individual hairs by 50%.

COUVRe Protein Hair Expander serum was designed to make your hair appear thicker and fuller instantly.

This product was designed with a high concentration of organic proteins, which are molecularly restructured to penetrate the exterior structure of the hair. This makes every individual hair appear thicker by 50%. The concentration of Keratin and botanicals gently swells your hair shaft on contact, significantly reducing the sparse areas of your scalp. 

You’ll see results after one application.


I am 60 and have thinning hair; tried many products. This is the one that gives me the most volume and texture. My hairdresser is impressed with this as well. The price is great and you don't need to use a lot.” Gretta H., - Ticino, Switzerland
