Rated 4 out of 5 by from Well behaved and smooth with a great smell [This review was collected as part of a promotion.] Really impressed with matrix. Had not heard of the brand before receiving the free sample, I swim frequently so have been using it post swim and it leaves my hair feeling soft and smooth even when air drying. Smells fantastic too! Have also spotted it creates more curl definition and eases frizz. Very impressed with my first impression of matrix and would buy in the future

Rated 4 out of 5 by from Real difference for frizzy hair [This review was collected as part of a promotion.] After just 2 uses I could see and feel my hair become smoother and glossier, improving its appearance by allowing curls to form naturally as frizz reduced while also reducing tangles. The shampoo and conditioner also both smell amazing.

Rated 5 out of 5 by from DEFINITELY RECOMMEND! [This review was collected as part of a promotion.] This shampoo changed my whole hair routine. SO SO GOOD. My waves have never looked better and the shampoo makes my hair so so soft, which i did not expect at all. Also it latter really nicely and it has so much foam from just a small amount. The scent of the shampoo is also fantastic and it lasts till the next day. I would definitely recommend in the future.
