What our customers are saying
I bought the trial size at the drugstore and it was great, so I bought the full size this time! I love how it leaves my skin shiny after rinsing.
I bought a three-day supply for travel. It leaves my hair smooth. I hate having frizzy hair when I travel, so it's very useful. The amount of shampoo and treatment is large enough for one use, so I don't have any problems. It also comes with a hair oil, which is convenient. It also comes with a one-use hair pack.
I bought the treatment. My hair is usually frizzy, but now it's calmer. I think the scent is really nice.
I received a sample of the shampoo and treatment, so I tried them out. The scent was lovely. It's said to be a sweet and sour, refreshing scent of rosehip blended with bergamot and lemon. The shampoo lathered well, and after rinsing, my hair didn't feel rough and was easy to manage. The treatment was easy to apply. The treatment didn't feel sticky, but had a smooth texture. It left my hair moisturized and smooth after drying. My hair was quite damaged, but it calmed and became well-behaved. My hair still smelled lovely the next day, so I felt great.
I've been using Hair Essence for many years, and I was also interested in the shampoo and treatment, but I've never had the chance to find them in stores, so I bought the trial set! It's very moisturizing, but I'm still debating whether to buy the full size because of the price...
