Daily anti hair-fall fortifying serum for weakened hair, prone to falling due to breakage.

Enriched with a potent combination of Aminexil, Edelweiss Native Cells and Ginger Root, the serum improves hair resistance to minimize hair-fall and maximize beautiful hair. It helps to re-anchor hair follicle more solidly into the scalp while building the optimal environment for future growth. Day after day the serum sooths and reinforces the natural protective barrier of the scalp. The jelly like texture facilitates the application and avoids any running of the product. Hair is stronger and more beautiful with a healthier look.

Directions

Use once daily in the morning or before going to bed during a 6 week period. Apply 4 doses on dry or towel-dried scalp, section by section. 1 dose = 1 pipette until the mark. Massage gently. Do not rinse. Style as desired.



Pro Tip: Use this fortifying anti-fall Serum once daily to minimize hair-fall and maximize beautiful hair .

Rated 5 out of 5 by from Worth every penny On my second bottle, I've been using for 6 weeks now. And I have noticed a huge difference with hair fall. Hair is starting to look thicker. Be prepared for hair growth as top of your head may looking messy with the baby hairs coming through. Also says use 4 pipettes. I use a full pipette (over the line) every 2 days.

Rated 5 out of 5 by from Holy grail hair product This is my holy grail hair product. I don’t know how many bottles I have purchased, but it really works. My hair is growing and I couldn’t be more pleased. I apply every night and it absorbs so well, it doesn’t leave your hair greasy at all, which seems miraculous and it has a lovely scent.
