This is a fantastically great and versatile hair serum for achieving the soft & shiny look without the added worry of flat iron hair damage.

It's a perfect fit for any hair type as it is suitable for fine thin hair, thick coarse hair and people with attitude issues. It works great and works fast.

The serum is water based and contains ionic sea minerals and multi-nutrient ingredients that help repair and strengthen the hair. It promotes the structural integrity of the hair and enhances shine by replenishing the scalp with vital nutrients and repairing damaged hair.

The hair serum also works as a thermal protectant for the hair leaving the locks free of heat damage and frizz. It also encourages and strengthens the formation of keratin protein in the hair which helps in the development of thicker and shinier hair.

I have fairly wavy and thick hair and it conditions the hair wonderfully without weighting it down. I was a bit dubious with the keratin protein claims when looking at the ingredients, but it really does help the hair be stronger and healthier.

My last keratin based serum was not only thick and goopy, but it was also hard t come off of hair and into the shower. This one is light-weight but very effective and easy to use. The serum also aids in strengthening the hair and repairing damage from heat styling.

A feature of ShampooSaloon that a lot of Keratin Serum product buyers will notice is how little this product costs, considering the effect it has on the hair.
