Pai-Shau: The Tea Infused Haircare

PR Samples - Affiliate Links

You know I love tea: I drink 5-6 cups a day of my favorite varieties, black Earl Grey and oolong mostly. So when I discovered a haircare brand that infuses their products with tea, I thought "hey, that's for me!". Pai-Shau kindly sent me their Opulent Volume Hair Cleanser, Opulent Volume Conditioner and Biphasic Infusion to test. Keep reading to find out if I these products convinced to use tea in my hair!

Every hair care product in the Pai-Shau line includes the brand's Signature Tea Complex: a blend of different tea varietals (green, white, black, Pu-erh, rooibos) that's rich in vitamins, minerals and antioxidants such as polyphenols. This complex is supposed to soothe and nourish the scalp while it strengthens and protects the hair. The products are also vegan and free of sulfates, parabens and gluten, and they are not tested on animals. The shampoo and conditioner I have are made in Canada, while the infusion treatment is made in the USA.

Pai-Shau is a professional brand used in salons, so you may be able to get it from your favorite stylist (they have a list of salons that stock the brand on their website). The hair salons inside Macy's work with Pai-Shau so you can also order their products online with Macy's usual free shipping, including their professional jumbo sizes (1 liter/33.8oz for shampoos and conditioner)!

My hair has always been an issue for me because it's hard to make it look good... It's very fine but wavy and slightly textured, so I'm very prone to crazy frizz all around my head, and it can look very flat and limp despite the waves. It's also not very shiny naturally and I usually air dry (if I blow dry I end up with a half wavy half straight mess). Based on my hair type I decided to try the Opulent Volume line from Pai-Shau to improve body and thickness, and the Biphasic Infusion to add shine and smooth the frizz.

A quick look through the ingredients list of this shampoo got me very impressed. It doesn't contain any of the harsh detergents that I avoid like SLS, and there's a ton of plant extracts. Not just tea, but a lot more! There's ginseng, white nettle and gleditsia seeds (locust tree), three plant extracts that compose what the brand calls Volumizing Botanical Complex. Pai-Shau told me that this complex adds volume to the hair in a way that's different from most other volumizing product: it is supposed to create a micro-bend in the hair instead of swelling the hair cuticle, so it is less likely to create damage.

The Opulent Volume Hair Cleanser features the scent that is common to the whole line: a floral, earthy fragrance that I find very gender-neutral. The shampoo is clear and it lathers a lot despite the absence of sulfates. A little goes a long way, and I would describe it as a clarifying shampoo: it provides a deep cleanse that removes any oil or product build up. My hair is squeaky clean after using it, and I can go 4-5 days between washes without it looking greasy. I don't find it drying (especially not paired with the conditioner), but if you have very dry hair or damaged hair you'd probably want to go for the brand's hydrating Replenishing Hair Cleanser instead.


The silicone free Opulent Volume Conditioner contains the same volumizing ingredients as the shampoo, along with some coconut oil. It's very creamy, and since it's on the thicker side I prefer to store it upside down in my shower so it comes out of the bottle more easily. It feels very nourishing and helps detangle my hair without having to pull. Paired with the shampoo, I get very clean but hydrated, healthy hair.


The Biphasic Infusion comes in a hefty glass bottle with a convenient pump that lets you see the two phases in the formula: the darker tea infusion sinks to the bottom, so you have to give it a good shake before use. This treatment has the same earthy floral and slightly musky fragrance as the rest of the line, but I don't find that it lingers in my hair.

I dispense two pumps in my hands, rub them together and begin working it into my hair, starting at the ends, then finish with the roots in order to tame frizz. I had my doubts about this "infusion" but I have to say that I'm really happy with what it does for my hair. It doesn't weigh it down or make it look oily at all, but it adds a good amount of shine and really diminishes frizz. It also does something for the texture that I can't really explain: it's like my hair looks... more expensive? I know it sounds stupid, but my hair just feels and looks like it's stronger and its quality has improved. I found decent products that help define my waves, but I had never found any leave-in treatment that makes my hair look this good.

3rd day hair
This is my 3rd day hair after using Pai Shau products for about a month!
My hair usually looks greasy and very limp by day 3 but not anymore.


With my Pai Shau regimen my hair looks fuller, stronger and shinier. My waves are nicely defined and my roots don't look greasy for a good 4 days. I'm really quite impressed with the products I have tried - I guess tea does great things for hair! I think the Biphasic Infusion is a treatment that anyone with damaged or dull hair would enjoy. As for the Opulent Volume shampoo and conditioner, they create a natural looking volume that works beautifully for my fine, limp hair.


Pai Shau is available online on the brand's website or at Macy's:
