This serum makes my hair look smooth, thick, and beautiful! I’m going to use this product consistently since I love how my hair looks from just using it. I recommend especially with those who have long dull hair!

A must have hair product!

I have used this for several weeks on my fine hair. It smells strong and invigorating! I like it. I got this in hopes of my hair becoming stronger and fuller. I will continue using this in hopes to seeing results.

Not for me

Too heavy for my fine hair. Overall it feels like a nice product if you have the right hair type for it.

This product is amazing! I noticed a difference within the first month of using it and loved the fact that it wasn’t greasy or oily. I will definitely purchase this product again!

A good thing to have on hand!!

I really loved the weightlessness of this oil. It wasnt sticky or super oily and dried quickly! My scalp felt great after using it a few weeks.

The formula is amazing!

This is a great growth-stimulating serum—ideal for filling in small patches where hair is sparse. It smells lovely, is super natural, and I love the packaging; I also love that it helps repair my scalp's barrier. I highly recommend it.

Good product

I really enjoyed this product, from the applicator to the scent and feel. I didn’t notice much of a difference in my hair, because I have locs, but my scalp was more moisturized.

Great

This is a light oil leave in serum scalp treatment for dry hair. It feels great on the scalp and leaves my scalp feeling fresh. I have not experienced any oil residue or build up.
