Holy grail oil
Ive tried a lot of hair oils, this one is *the one* for me. I have fine hair, medium length, and its hard to find an oil that isnt too heavy or greasy. This oil is amazing! Well worth the price tag.

New formula - SO DISAPPOINTING
This shampoo, conditioner, and the serum have been my favorite for years. I had tried the new serum first, and noticed it didn't make my hair nearly as soft as the old bottle.

Wow! Impressed
Hair Type Wavy Hair
You know a product is good if it makes a difference with the first application and this one definitely did! Worked great for my daughters hair too that is a completely different hair type.

Love this!
I usually don't leave reviews, but this hair serum was so good I have to!! It smells amazing, goes on well, and it left my hair so soft and hydrated. I will 100% buy this again!!
Holy grail
I have never loved a hair product more and I have tried a lot… if you want soft hair without the weight this is the one!! Bought on a whim when it was on sale, im hooked.
It's OK
My hair is extremely reactive to humidity. Think Monica from the "Friends" episode when they went to the beach. This product initially gave me a smooth finish, but it didn't hold up all day against humidity. I have another oil I've used for a long time, and I didnt really like this product any better than that one, so I returned it.
This oil slaps
Apparently I did not read what this stuff really was and bought solely because of the reviews and on sale during the 21 Days of Beauty, but my first impression. The smell. It smells great! My eight year old daughter also got the same first impression too when I used it on her hair today. And healthy look and feel. Got me as a repeat customer first use. She's thar girl! Get it!
