I've been using the 500ml size for a while now, and it's been giving me headaches ever since the product was renewed. I regularly get bleaching and coloring done, so I'm quite particular about my shampoo and treatment products. While I use professional-grade treatments, I've tried many different shampoos but haven't been fully satisfied. My scalp is sensitive due to the coloring, and I often have a lot of dandruff. But this product doesn't cause any itchiness or excessive dandruff, even when I use it daily. The lather is also very rich, so I don't need to use much to cover my long, voluminous hair (just two pumps). I've been getting a lot of compliments on the condition of my hair, and the hairstylists at the salon say my hair looks healthy even after repeated bleaching. It's a bit pricey, but I can't bring myself to switch to something else. I'll have to try the renewed version this time.

Even a small amount of pumping creates rich lather The scent is not overbearing It doesn't leave my hair feeling dry and brittle without using conditioner, rinse, or treatment - I really like that. It works even better when used with a conditioner Buying it on sale is a great deal, so I recommend watching for sales. Purchasing the large size means I can use it for a long time, so the cost is not a big burden.
