Reviews

Best hair mask I’ve ever used

"I have 3A curls that are relatively fine-stranded but I have a LOT of hair, which is why I bought the thick masque. It’s so soft and makes my hair feel like silk. Probably the best hair mask I’ve ever used."

— Megan S. (5/5)

Makes my hair feel incredible

"I have thick wavy hair down to like my hip bone and my hair dries out very easily. So i love using this every other wash day because how it make my hair feel rehidrated all the way done to the very ends of my hair . Even though its pricey i think thats its worth it and it last a pretty long time if you don’t use it every day/ overuse it."

Q&A

can i use this product with conditioner before applying or should i skip conditioner?
Hi Alexa! You may skip conditioner and put our Thick Hair Treatment Masque after shampoo. We recommend you to use it weekly or bi-weekly. After cleansing, remove excess water from hair. Apply a quarter-size amount starting from the ends and working to the roots. Comb product through with fingers or wide tooth comb. Chill out for 5 minutes, then rinse with cool water. Hope this helps!
Is this safe to use with a keratin or straightening treatment in your hair? Meaning it won’t take out my keratin or smoothing treatment.
Hi Zoe! All of our products, including our Treatment Masques, are safe for keratin-treated hair. All OUAI products are free of sulfates, parabens and phthalates. As always, it's best to consult with your stylist before starting any new products after a Keratin treatment!
