Busy. Tired of spending money to try to find a good product. Tired in general. Got better things to do than troubleshoot why your hair is acting like an unhinged psychopath? Does this sound like you?
I could pitch you some expensive, fancy, salon or prestige product and you could spend an arm and a leg on it…
…or you could just chill and get Costco’s liter-sized Kirkland Signature Shampoo and Conditioner.
While I’m a content Costco customer, don’t worry – I’m not a sample-rabid zombie. I just appreciate a good value – and Kirkland Signature Shampoo and Conditioner is certainly that.
Since my hair loss disaster (I’m all better!), I switched primarily to the wholesaler’s in house product. I didn’t do extensive product testing or sampling; I just picked it up in my usual groceries because my time is currently at a premium.
Why?
First, Quality
The formulas of Kirkland Signature Shampoo and Conditioner are salon-tier, and that is not just marketing hype. We’re talking a sulfate-free conditioner (its main surfactant is used by Ethique bars). It is gentle on my balayage, doesn’t dry my hair out, make it brittle, make it flat, etc.
