What it is
Most shampoos clean and that's it — moisture gets stripped along with the buildup. The 8 THE THALASSO Repair & Moist Shampoo works differently because it functions more like a serum that also happens to lather. The creamy foam feels gentle on the scalp, rinses clean without that squeaky-tight feeling, and what's left behind is noticeably different: hair that feels plumper at the mid-lengths, smoother at the ends, and easier to detangle while still wet. The aqua white floral scent is fresh without being heavy. It's the kind of Japanese scalp shampoo that rewards continued use — the longer you use it, the more balanced and less dry your scalp tends to feel, which eventually shows in how your hair behaves between washes.

How to use
Thoroughly wet hair and scalp with warm water. Pump an appropriate amount of the 8 THE THALASSO Repair & Moist Shampoo into your palms — typically one to two pumps for medium-length hair — and lather between your hands before working it into the scalp. Massage in circular motions to work the lather through from root to tip. Leave for a moment if your scalp needs extra attention, then rinse thoroughly until the water runs completely clear. Follow with a conditioner or treatment for best results, especially on dry or chemically treated ends.

The shampoo lathers well and gently removes sebum and styling products. It also contains plenty of beauty serum ingredients, so your hair won't feel stiff after washing and will be moisturized and manageable.
I've seen it recommended a lot on social media and in stores recently, so I was curious and decided to buy it! It makes hair that tends to get dry and tangled due to dryness, coloring, and heat damage more manageable! It's exactly how my hair is right now, so I wondered if a shampoo and treatment would really make a difference, but I could see a big change after just one shampoo! It charges moisture from the core, leaving hair moisturized and shiny all the way to the ends! It's easy to wash with, and the aqua white floral scent that spreads the moment you lather it up is a wonderful scent. ◎ Even after drying, my hair feels moisturized and manageable, and I can keep it looking beautiful for a long time! It's made styling my hair so much easier, and it's also easier to run my fingers through, so I recommend it♪♪
The scent and feel are good.
I couldn't find a shampoo and treatment that I liked, so I tried a variety of products, from cheap to slightly more expensive, but this shampoo and treatment was by far the best! The more I used it, the better my hair became, and it helped me with dryness and frizz, so I highly recommend it. I think it can be used by people with pretty much any hair type! The scent is also elegant, so it can be used by both men and women.
[Testing 200 Shampoos] No. 149 Thank you for viewing! Following me encourages me to post more! ★ 20s Hair Type: Thick Bob / Bleached (2-3 times) I've been eyeing Eight the Thalasso for a while now at the drugstore. I first bought the trial size. The scent is aqua white floral, a gorgeous, clean scent! I love it!! It lathers up really well, with a bouncy, fluffy lather!! It leaves my hair moisturized, not sticky, and smooth to the touch. It's a shampoo I'd definitely like to repurchase.
