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 Amazing!! I’ve used this product 3 weeks ago and it is so effective!! Easy application, absorbs quickly and it’s easy to concentrate on the areas that need help. I normally used to loose a lot of hair during each bath and today it’s been just a few instead of handful! Get it for yourself it’s worth every penny

Rated 5 out of 5 by from Miracle Serum Bought it to help with hair loss. I have seen great improvement when I was my hair, it has significantly reduced the hair fall. The only issue I have is that for the price, it doesn't last very long. It doesn't leave your hair greasy and has a lovely clean scent, which doesn't irritate my sensitive/eczema prone scalp.

Rated 4 out of 5 by from Great product One of my favourite serums as it doesnt leave my hair greasy or any residue after applying. Ive been using for about a month and have started to notice a lot of growth around my scalp. Only a little bit of product is needed, i do usually about 2 droppers for the best usage!

Rated 5 out of 5 by from Only product that works for my hair loss I have tried many products and this is the only product that actually reduces my hair loss and I have been using this consistently a few years now. It is easy to apply, however I do recommend to only use one pipette each time as it will finish very quickly if you do the recommended concentration on the bottle.
