After doing some research online, I discovered that Costco had a possible dupe: the Kirkland Moisture line. Personally I'm not a Costco member, but luckily my boyfriend is. Like Pureology, Kirkland Moisture is sulfate-free, paraben-free, and 100% vegan. Unlike Pureology, it's extremely affordable. So on our next trip to Costco, I picked up the duo to try them out.
Before I get to the reviews and comparison, here is a brief description of my hair type. I have naturally wavy hair (2a curl type) that's not very thick, but it is pretty voluminous. When there's a lot of humidity, it turns kind of curly and frizzy. My scalp is on the oily side, so I usually need to wash my hair every 2-3 days. However, my ends are dry, so when I go too long without a haircut, I tend to get split ends. Nowadays, in addition to shampoo and conditioner, I use a leave-in conditioner every time I wash my hair, and I apply a hair mask every couple weeks. I usually let my hair air-dry (which gives me slightly wavy hair), but sometimes I blow-dry (which gives me mostly straight hair).

Shampoo Comparison
This shampoo smells very herbal/medicinal, which I don't really like. Also, it hardly lathers at all, which I also don't like (typical of sulfate-free shampoos though). However, it is very moisturizing. On the first day after washing, my hair looks great. The ends feel very soft and smooth. On day 2, my roots start looking oily, and my scalp feels a little itchy. I have to resort to using dry shampoo, which I normally don't need until day 3. On day 3, my scalp feels pretty itchy, like there's too much oil build-up. When I use this shampoo, I need to wash my hair every 2 days (instead of 3) to avoid the itchy phase. In terms of price, a 1.7 fl oz bottle of shampoo costs $7.50, a 8.5 fl oz bottle costs $28.50, and a 33.8 fl oz bottle costs $66.
Summary
- Pros: Very moisturizing
- Cons: Smells very herbal/medicinal, causes too much oil build-up/itching, expensive
This shampoo smells sort of sweet and floral, which I like better although it's still not my favorite scent. I really like how it lathers like normal shampoo. It is also reasonably moisturizing, although not as moisturizing as the Pureology Hydrate shampoo. My hair looks pretty good on day 1, and my ends feel very soft compared to when I use normal shampoo. On day 2, no scalp itching, but my roots start to get a little oily. By the end of day 3, my roots feel too oily again, and my scalp is a little itchy, so I need to wash my hair. In terms of price, a 33.8 fl oz bottle costs $9.99 at Costco.
Summary
- Pros: Pretty moisturizing, affordable
- Cons: Still causes a little too much oil build-up
WINNER: Kirkland Moisture Shampoo
Conditioner Comparison
I love this conditioner! Out of all the conditioners I've ever tried in my life (mostly drugstore), I think it does the best job of smoothing and moisturizing my hair without weighing it down (I only apply it to the ends). Also it smells really good, like peppermint. Used in combination with my holy grail leave-in conditioner, my hair looks and feels great. However, it is pretty expensive. A 1.7 fl oz bottle costs $7.50, a 8.5 fl oz bottle costs $30.50, and a 33.8 fl oz bottle costs a whopping $68!
Summary
- Pros: Great for smoothing/moisturizing, weightless
- Cons: Price
This conditioner smells very similar to the shampoo, i.e. sweet and floral. Personally I prefer the clean peppermint scent of the Pureology conditioner. It's also very good at smoothing and moisturizing, but it's not quite as weightless as the other one. However, the price is much much better. A 33.8 fl oz bottle costs only $7.49 at Costco.
Summary
- Pros: Good for smoothing/moisturizing, not quite as weightless, price
- Cons: None
WINNER: Pureology Hydrate Conditioner (by a hair, pun intended)
-----
Overall I'm impressed by the Kirkland Moisture line, and I highly recommend it. I think it really is a good dupe for the Pureology Hydrate line, and the value is amazing when you consider how much product you get for the price. Kirkland is a Costco-exclusive brand, but even if you're not a Costco member, you can buy the shampoo and conditioner online through Amazon. Once I use up the Kirkland Moisture conditioner (it's a huge bottle), I think I'll switch back to the Pureology Hydrate conditioner though.
Anyway, I hope you enjoyed this comparison! Do you use sulfate-free products? Have you ever tried plopping your hair?
