With REIN our goal was to design effective and luxurious formulations that delivered on dandruff control as much they did scent, texture and touch.

We engaged one of Australia’s top GMP (Good Manufacturing Practice) certified chemists to produce a cruelty and toxic-free formula that was revised nine times before we arrived at our final product.

Originally, we tested only natural ingredients but they simply were not effective in reducing dandruff. After comparing research on the efficacy (effectiveness) and benefits of synthetic antifungal ingredients; namely, Piroctone Olamine and Ketoconazole, we settled on the superior Piroctone Olamine. PO was found to be more effective in reducing the amount of dandruff and, at the same time, provided hair conditioning advantages. In a controlled clinical trial of hair shedding and thinning associated with dandruff, the study concluded that 1% Piroctone Olamine saw improvement in their hair shaft diameter by 7.7%, compared to 1% Ketoconazole (5.4%) and actively decreased sebum production, while reducing hair fall by 16.5%. 

We tested Piroctone Olamine with Zinc Gluconate and acheived amazing results in just six weeks, following which we introduced a range of moisturisers, stablisiers, extracts, and oils, noting changes in colour, smell, viscosity, lather, scalp invigoration and, of course, effectiveness. With 2-in-1 products lacking the ability to perform either role sufficiently we also designed a conditioner to restore moisture following our shampoo. The formula is complementary to the shampoo, carrying across the same scent and essential oils but replaces active ingredients with oils, butters and proteins designed to reinvigorate the hair and scalp. 

As you can read from our products reviews, customers are loving it.
