Return to a clean slate for healthier hair growth with this gentle daily shampoo. Lightweight and non-irritating, the formula helps improve the scalp environment and enhance the restorative effects of our Saisei Biomimetic Peptide Treatment Essence. 

Saisei Stress Defense Amino Acid Shampoo’s blend of amino-acid and coconut-based surfactants thoroughly cleanse the hair and scalp without stripping moisture. Botanical ingredients such as apple extract and rosebay extract help soothe and hydrate the scalp to aid reduction of hair loss and sebum production. Naturally resilient and antioxidant-rich black spruce bark extract and bamboo extract work increase protection against oxidation and environmental stressors such as UV exposure. Strands are left feeling refreshed and rejuvenated.  

Designed to be used in a daily routine with the Saisei Restoring Therapy Conditioner and Saisei Biomimetic Peptide Treatment Essence.

Scalp health is essential for healthy hair, and an imbalanced scalp that isn’t well cared for often leads to other issues like irritation, dryness, and excessive oiliness. Keeping the scalp hydrated and maintaining the skin barrier are key ways to aid protecting the scalp from irritation and support an optimal environment for healthier hair growth. Rosebay extract, a plant that is able to regrow and thrive even in areas affected by wildfires, helps soothe the scalp along with apple extract. Anti-inflammatory and vitamin-rich seaweed extract and algae extract help add and retain moisture.

Reviews

Scent is not for everyone, not for me

"I did not like the scent of this product, I used it once and just could not get past the scent. Not for me."

— Kelly K. (2/5)

"I love everything about these products"

— Lanai (5/5)

Just what my hair needed

"The Saisei shampoo has a delightfully fresh aroma and lathers easily. It leaves my hair feeling stronger, fuller, softer, shinier, and my scalp rejuvenated and healthy. The conditioner is very light weight and it covers the hair easily. It smells great and leaves my hair feeling well conditioned and easy to comb through."

— Ziggypiggy1020 (5/5)

Smells great!

"I enjoyed using NatureLab Shampoo and conditioner. I have very fine hair, and although while washing and rinsing it felt as if my hair was going to feel flat after it drys, surprisingly it didn't. Your hair will feel really silky after, and have less frizz. I wish the formula was a tad less thick, because the lather could be more. The scent smells great too!"

— Lulu480 (4/5)

Great product

"I love a shampoo and conditioner combo! I’ve used the shampoo conditioner, a couple times and my hair feels so smooth. I almost feel like I’m also losing less hair when I brush it out. Very happy with the results so far. Easy to use containers."

— Rabiaq2 (5/5)

Smells amazing

"I received NatureLab. TOKYO Saisei Shampoo + Conditioner Duo from Influenster in exchange for my honest review. I am absolutely obsessed with the fragrance of this shampoo and conditioner. It smells like I am in a spa. The shampoo and conditioner made my hair feel great both in and out of the shower. It made my hair feel so sleek and made it much easier to manage and style. Looks great. Feels great. Smells great."

— Delphinidae (5/5)

Leaves hair soft and lifted!

"I was skeptical of this shampoo and conditioner because I don’t love how the packaging looks but if you look past that, the products themselves are great! I do have thinning, graying hair that I have to dye and this shampoo and conditioner didn’t turn my hair brassy at all and left it soft and lifted even with silicone in the conditioner. Will purchase again!"

— Tinasaurusrex (5/5)

Repair damaged hair

"The bottles at the beginning are not to easy to open, I almost get one of my teeth out trying to open it so this should be something to consider in the future. The shampoo helps you clean your scalp while the conditioner helps you to repair the damaged hair I have been using it for 2 weeks already and the changes are huge you can see the difference si ce the beginning once you apply it"

— Ariannat4ef7 (5/5)

Great

"Great shampoo & conditioner from Nature Lab Tokyo. The shampoo has a subtle cucumber scent. It is gentle but very cleansing on the scalp. The conditioner is amazing, reduces frizz even if you airdry afterwards. New to me brand, i will definitely check their products."

— Melodi (5/5)

My Husband & I Love the scent

"First impression was I love the shape of the bottles, very aesthetically pleasing. Once I started using the shampoo, I instantly enjoyed the scent! It’s light, clean & calming. It lathers well, my hair & scalp feel clean after using. The conditioner gives my hair the hydration it needs to run my fingers through it & afterwards it feels healthy & soft. I really enjoyed using these! My Husband even comments how much he loves the way my hair smells with this shampoo & conditioner."
