Great product

I’ve been using the serum for a few months now. I’ve noticed my hair is definitely growing and my hairdresser confirmed it when she colors my hair . She says I have a lot of new growth coming in! I will continue to use it!

Experience is fantastic. Hair products are definitely recommended as it gives my hair thickness and volume.

Product is great, really works...

it is really great product, really nice odor and no residue on scalp
