I bought this product for R15.99 at Clicks. This product was recommended by my cousin who is a bit of a flat-ironing junky and not too diligent with the heat protectant. She has had problems with breakage and dryness and told me this mask literally saved her hair. I applied it to freshly shampooed hair and left it on for 45 min. When they say tingling intensive they’re not kidding. The minty feeling on the scalp is very strong initially but subdues after 20 min. The treatment rinsed out easily and even removed the residual staining I had on my scalp from dyeing my hair. After rinsing and drying my hair I could feel the difference. My hair feels soft and looks shiny. It might be a little too heavy for fine hair. I’m not sure if it does really promote hair growth but I will definitely be using this product again as a once a week deep conditioning treatment especially after colouring my hair.
