"New"
"👍"
"So far so good first time I’ve used this particular product I do like it it’s just I haven’t had it long enough to really judge whether it’s working or not but I do like the product it does smell good and everything else they have works so I’m sure this is great as well"
"My gray strands were becoming far too noticeable on my very dark brown hair, and even deposit-only hair dye was causing thinning/breakage. I’m almost through one bottle & a few not-gray hair sprouts are coming up. No change to current grays as of yet but will continue to use to see further improvements, hopefully. Only side effect is slightly oiler scalp but not a major concern."
"Wish I’d known about this earlier. Relief within days and no scalp dryness. Trying the other products too."
"A very convenient to use and effective serum spray that sinks right in. Effects start to show after 3-4 weeks of continuous use but it is worth it"
"I am not done with my bottle yet but I am SO impressed. My hair has stopped falling out and I can see massive baby hairs growing. Plus it feels and appears so much thicker"
"I absolutely LOVE the Saisei Biometric Peptide Treatment Essence! It feels like a nourishing spa on my scalp! I've used many products like this one to combat thinning and aging hair but none have been successful. My hair is feels amazing now & the color is vibrant. Thank you Nature Lab Tokyo!"
"So far so good! I bought this product solely for growing and thicker hair, as I’m not experiencing greys (yet). I have definitely noticed growth in the past 3-4 weeks, so I am planning to continue using and thinking about purchasing more to have on hand. Also, personally, I have found that a little goes a long way-which is great as the bottle is quite small. My only gripe and reason for the 4 stars-and not 5-is the size of the bottle is so small. Wish it was a little bigger to last me longer."
