Thicken Biotin 5-in-1 Leave-In Spray, 6 fl oz | Biotin leave-in spray, for fine, thin hair, adds fullness and volume, with collagen, sulfate-free, color-safe

This is the best spray on 5-In-1 product I have ever used. It not only protects my hair from blow drying, it can be used on dry hair to recreate the shiny softness of a fresh shampoo. Its thickening ability is incredible but not stiff. I don’t understand why it’s not available anymore in stores like WalMart or Target. Thank goodness for Amazon!! Don’t ever stop making this product HASK!!!

Love this spray so much, I’ve been using it for several years now. Smells heavenly.

This is a great product and great price.

I’ve been using this product to help my hair feel softer and appear thicker since losing all my hair from Chemotherapy!!

It works great, but smells like men's cologne.

I love this spray! It helps get rid of the tangles in my hair and makes it feel great all day! Plus the fragrance is great!

I like this

This is a great product, but I bought it for $6.97, now, you want over $12 dollars for this?! Sorry, it’s still $6.97 at Walmart, and they deliver also. $12 dollars, is an absolute ripoff!!!

Le spray pour les cheveux à la biotine et vraiment fantastique pour les cheveux je suis très contente mes cheveux sont de plus en plus beaux grâce à ce produit n'agresse pas les cheveux au contraire je suis très contente rien à dire je remercie Amazon de mettre des six bons vendeurs sur leur site ❤️❤️❤️❤️❤️❤️❤️❤️💋

رايحه لا باس فيها ..لكن المنتج مايفك التشابك ولا يهدي النفشه ولا يرطب ماله اي فايده

Absolutely superb for blondes. Leaves my hair shiny, soft and smooth. Highly recommended

I first used this while staying with a friend and loved it so much, I placed an order before getting home. It smells so fresh and clean and my hair feels good after use.

Habe sehr dünne Haare und mit diesem Spray wirken sie nach dem Trocknen griffiger und fälligen.
