Mind browsing service. I had questions but all were answered and solved by just a telephone call by a very knowledgeable and incredibly helpful lady. She was also super patient and pleasant! Products are also amazing. I am very happy with almost all my purchase. The only problem is that the colours tend to come out much darker than what they are named. I tried Natural Dark Brown (3N) and my dark brown hair became almost black. It took me quite a lot of time and effort to get rid of the darkness. Now found the Rich Copper (5R) and absolutely loving it. Because my hair is already naturally dark brown, the colour does not make my hair red but gives the most beautiful warm milk-chocolate like seen while my grey hairs get perfectly covered with nice 10p coin copper colour which acts like very subtle highlights. Also it is much gentler on the sculp compared with other naturally derived hair colours. I still get a bit of itchyness the day after but it is not too serious. Hydrate Shampoo, Hydrate Conditioner, Hydrate Treatment, Leave in Conditionet, Hydrate Treatment and Structure Treatment are all excellent, My hair was very damaged and porous but using Structural Treatment and Hydrate Treatment similutaneously improved the condition drastically. I also use Leave in Conditioner before I straight my hair as a heat protector, i do not know whether it is a right ting to do or not but seem to work very well.
