Suggested Use

Scrunch out excess water section by section using your hands to better define curls, or plop your hair into a microfiber towel.

Follow with the Styling Gel, scrunching the curls for maximum definition. The more gel you add, the stronger the hold.

Let hair air dry or heat dry with a diffuser.

About to order a fourth tub

This gel has become a holy grail styler for me. My hair is wavy and heavy, so I use the 123gel styling method. I start with a flax seed gel for moisture, use Kerotin gel for protein, and then top with a hard hold gel for hold. My waves spring up when I scrunch Kerotin gel into it. Kerotin, please do not ever change or discontinue this product. I am about to order my fourth tub of this.

Bouncing Curls

Love the results I achieved with the Curl Line Duo. Naturally, curly, grey hair can be challenging in general, and my hair is no different. Moisture retention, definition and manageability are my hair's three problems areas. After using the Leave-In Conditioner and Gel, I got the results I was looking for. My foam rod set results were defined, bouncy curly hair!

Curly System

My hair loved the Curly Leave-In Conditioner and Styling Gel. It left my hair moisturised, curls defined, bouncy, soft to touch with a good hold for 4 days. I think it would’ve lasted longer if I wasn’t in the rain and wind so much over the 4 days. I love the smell of the two products, both have a light and fresh scent. Nothing too over powering.
