Kérastase Sprout Serum for Full Hair

My scalp has been looking thinner and losing volume lately, so I started taking care of it! I'm paying attention to my shampoo and conditioner, and I'd like to introduce the Kérastase Densifique Sprout Serum that I've been using a lot lately.

It's convenient because you just have to spray it on your scalp.

The downside is the price!

Still, one bottle lasts quite a long time!

I think it helps with fine hair.
