[Testing 200 Shampoos] No. 150 Thank you for viewing! Following me encourages me to post more! ★ 20s Hair type: Thick bob / bleached hair (2-3 times) The scent is a white floral air, with a gorgeous fresh floral scent. It has a slightly strange flavor that I found a little hard to handle. The lathering wasn't great!!! I thought it was because I was using wax, but many reviewers have said the same thing, so I think that's just how the product is. However, the finish was amazing, giving my hair a beautiful shine. What's more, my hair looked neat and clean all day the next day, which I thought was amazing! It felt like silky hair that never got tangled!! It's been such an amazing experience!! If the lathering had been better, I would definitely have bought the actual product...
The texture after washing was to my liking, but the smell was a bit strong.
I like the lather and the scent. It's designed for thick hair, so I was a little worried about my thin hair, but it was no problem at all. It doesn't get sticky or dull at all. The condition of your hair changes depending on the season, so it's good to use different products depending on the season.
Hair type: Medium thickness, prone to dryness. Hair condition: bleached. I also purchased the Sleek Moist to compare. The Sleek Moist was good, but because my hair is bleached, this Deep seemed to retain moisture better. It makes my hair softer. Also, the scent is strong while washing, so I think it would be a relaxing product for people who don't mind strong scents. The scent isn't as strong once it's dried.
