Deep Conditioner Hair Treatment

Soooo moisturizing!

I’ve tried many, many hair products and treatments for my dry, tends to frizz hair. I really can’t say that about my hair any more since I’ve been using GK products. I received a sample of the deep conditioning hair mask and absolutely loved it so much that I purchased a jar of it! I use it in conjunction with GK shampoo and conditioner. I constantly get compliments on my hair thanks to GK!
