Everyone’s hair is different, meaning particular ingredients and products work better for some than others. But every now and then, you’ll encounter an all-star! Yes, those universally beloved ingredients that check all the boxes. And would you believe there are still some out there that haven’t gotten the recognition they deserve? 

Case in point: green tea seed oil. Extracted from the seeds of the Camellia sinensis plant, the oil is a key ingredient in NatureLab. TOKYO’s restorative Kiseki collection. Its purpose in our oil and leave-in hair masque duo? It adds moisture to the hair, making it easier to manage with better protection. But our general appreciation for this ingredient goes so much deeper. 

Western culture has embraced green tea as a powerful antioxidant known to help protect against diseases, improve brain function and even aid with weight loss and blood sugar regulation. And taking the multifaceted ingredient a step further, in Japan, skincare enthusiasts regularly use green tea seed oil to fight acne, signs of anti-aging and irritated skin—thanks to its antibacterial and anti-inflammatory properties. Despite its classification as an emollient, the lightweight consistency doesn’t leave a greasy finish, and is typically considered non-comedogenic (meaning it won’t clog the pores).

Sustainability is a key pillar of NatureLab. TOKYO’s product portfolio. That’s been especially apparent in sourcing for our Kiseki collection. Extracted from byproduct tea seeds on a leading Japanese tea farm, we were able to support local culture while protecting the environment. 

How to Maximize Green Tea Seed Oil Benefits Using NatureLab. TOKYO Products

Our Kiseki Molecular Repair Leave-In Hair Masque—which blends green tea seed oil with lotus flower extract, milk thistle and pea protein—helps protect the hair cuticle from environmental stressors. The green tea seed oil, specifically, adds moisture to make the hair more manageable and protected. Our formula’s components feature a well-balanced range of molecular weights to repair hair at each layer. 

Additionally, key peptides are able to penetrate the hair’s surface and deliver their benefits inside the hair’s cortex due to their lower molecular weights, while smaller molecules are able to go straight to the core. Other ingredients can adhere to damaged areas in the middle layers and at the cuticle surface for thorough repair at every level. Excuse us for tooting our own horn here, but this leave-in is pretty remarkable! 

The masque works best when applied in conjunction with our Kiseki Molecular Repair Mizu Hair Oil. The final step in an overall hair routine was formulated to help reverse damage, leave strands silky smooth and shiny, and replenish moisture, reduce frizz, seal split ends and improve overall texture. We especially recommend it for users with color-treated hair, breakage or in need of deep moisture. 

And, for even deeper revitalizing benefits, we recommend kicking off your routine using our Repair Shampoo + Conditioner. This ultra-nourishing pair was formulated to restore dry and damaged strands.
