Perfect for fine wavy hair

I've been using this after the freshening shampoo and conditioner for the past 4 months. It is spectacular! I was suffering hair loss on top of already fine low density hair. The texture was changing due to menopause. One big nightmare after another. This product helps seal off my hair without weighing it down and gives it the perfect base for my styler. Absolutely love this. Have told friends. Will buy forever!

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.
