LOVE THIS STUFF

This reminds me of a favorite product from the 80's that is no longer available so I'm very happy to find this product. It gives you THICK ENDS. Who doesn't want thick ends? You can rinse it out or leave it in. you can use a little or a lot and you can direct where you use it. Roots? Ends? Mids? This is an Excellent Product. LOVE.

Amazing results. What's not to love.

I purchased this product i must say with a little wariness that it would actually work. I have tried others before with sadly no different. I was pleasantly surprised. It does what it says on the tin. Hooray to thicker hair.

Good

This hair treatment is so good. In general this mark works well. Especially this hair treatment contains biotin to strengthen hair and improve its vitality, ginseng root extract to reduce breakage and promote a healthy scalp, and quinoa seed extract to repair and protect the hair’s cuticle. Hydrogenated castor oil adds shine to tresses and locks in moisture.

I had a sample of this and used it, I was surprised as my hair is curly but fine and it made it feel heavier so the curl was better, I loved it and purchased the product

Volume Boost in a Bottle

The R Co Dallas Biotin Thickening Treatment has been a game-changer for adding volume and thickness to my hair. This treatment is packed with biotin, which strengthens and supports hair health, and it really does deliver on its promise to make hair look fuller and more voluminous. I apply it to damp hair before blow-drying, and I immediately notice a difference in the body and texture. It doesn’t weigh my hair down or leave any residue, and it has a light, pleasant scent that makes the experience even better. My hair feels softer, looks thicker, and has a noticeable lift that lasts throughout the day. While it’s a bit of an investment, the results make it worthwhile, especially if you struggle with fine or flat hair. For anyone looking to boost volume and strengthen their strands, R Co’s Dallas Biotin Thickening Treatment is a fantastic choice. It’s like giving your hair a bit of extra life in every spray!
