This is some of the best hair serum on the market not heavy very light and smells amazing!!!! And the shine it leaves is great but it doesn't look greasy.

I love this serum it is very light weight and it does hydrate my scalp and hair . I use this as a final finish for my hair

Loved that there wasn’t any residue after the application!

I never liked an oil in my hair, since it always makes it greasy and feeling gross. But this serum doesn’t, and it really hydrates my scalp and fights the frizz

When I tell you I love this serum! I truly do. It’s light weight and does not sit on top of your hair like many other oils/serums I’ve used. Some oil cause me to breakout as well and this has not. I’m heavy handed but a little goes go a long way.

It hydrates and repairs my hair since it is bleached, it feels soft and it doesn't make my hair greasy. I use it when I finish drying it.

My hair is silky and soft. My twists are bouncy and healthy.

This oil actually penetrates the shaft and softens the hair. I’ve used it on wet, damp, and dry hair and each time, the results were amazing. It’s a small bottle but it’s an integral part of my hair care routine. Thank you 🙌🏿.

It’s not too sticky, or overly fragrant. I used it to spruce up my roots daily. Seems to do its job.

This serum is amazing! My hair is softer, shinier, and healthier than ever. Highly recommend.

This serum is a miracle worker! My hair was so dry and damaged, but after using this, it's softer, shinier, and stronger than ever. Highly recommend!
