Love it! ### ⭐⭐⭐⭐⭐ Love this shampoo and conditioner *by K***K on September 19, 2026* Smells nice and makes my hair softer and more manageable than any other shampoo I've ever used. You don't need a lot either. ### ⭐⭐⭐⭐⭐ Worth the high price *by S***T on May 21, 2026* This is the best shampoo and conditioner I've found for frizzy hair, which isn't to say that it has eliminated the problem. Maybe that's too much to ask for someone who's almost 85 years old to ask. The biggest problem is getting the conditioner out of the bottle as it is very thick. I use a tiny spatula made for cosmetics but I need to dip it several times. I would prefer if the conditioner came in a jar with a large opening. The price is high but a little goes a long way. I expect to reorder. ## Frequently Bought Together - OUAI Thick Shampoo and Conditioner Set - Sulfate Free Shampoo and Conditioner for Thick Hair - Made with Keratin, Marshmallow Root, Shea Butter & Avocado Oil - Free of Parabens & Phthalates (10 Fl Oz) - OUAI Leave In Conditioner & Heat Protectant Spray - Prime Hair for Style, Smooth Flyaways, Add Shine and Use as Detangling Spray - No Parabens, Sulfates or Phthalates (4.7 oz) - OUAI Hair Oil - Hair Heat Protectant Oil for Frizz Control - Adds Shine and Smooths Split Ends - Color Safe Formula - Paraben, Phthalate and Sulfate Free (1.5 fl oz) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/271764406-thick-hair-shampoo-and-conditioner-set-10-oz](https://www.desertcart.pt/products/271764406-thick-hair-shampoo-and-conditioner-set-10-oz) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-06*
