GIOVANNI Biotin & Collagen Hair Serum - Hair Strengthening, Smoothing & Styling, Vegan, Cruelty-Free, Infused with Natural Botanical Ingredients, Salon-Quality, For Healthy-Looking Hair - 2.75 Oz

I added this serum to my post shower serum routine with the Hemp Oil serum by the same brand and my hair game busted to the next level. As a 3b/3c curly haired person, I've been looking for a routine that can help with softening and strengthening my hair and this addition was absolutely it. Two pumps of this and two pumps of the Hemp oil applied to wet hair will make your curls soft and bouncy and silky just like the straight haired people on the commercials!

I love this product. My hair has been over-dyed and it's usually dry looking. This product gives me a shine, and my hair doesn't look as dry. I love it.

This is the second bottle of Biotin Serum for hair I have purchased. It has a lovely scent, it is light weight for my very fine hair leaving it with a bit of lift, and it leaves a nice shine to my snow white hair. I love it.

I really love this product. It keeps my fly away hair calm and smooth with just blowdrying. I love the scent, I will still buy this but it is 5.00 more here than I have found in Marshall's per little bottle.12.99 still isn't bad, just wish it was the 7.99 that it was in the store:)

Perfect

Funciona muy bien

Excellent product. It doesn't leave the typical residue feeling on your hair or hands and makes my hair incredibly soft and smooth. Giovanni for the win again!

This GIOVANNI Biotin & Collagen Hair Serum did not work well for my curls. Could be that it just doesn’t play well with my other products (LUS) or maybe it is meant for my straight-hair sisters, but it made my hair stiff in a way I did not like. Another thing I did not love is the scent. I am sensitive to floral smells like lavender and rose. It didn’t bother me too much as it’s s not very strong, but something to be aware of if you are similar.There is a claim of natural ingredients and they are there…along with some others. I’ve included a picture of the ingredients so you can judge for yourself.
