I know Aromatica is a pricey brand without discounts and that also aligns with my wish that the price for the shampoo would give me a bigger bottle. However, when using it the shampoo was quite concentrated so I didn't have to use much to get some suds. I can't attest to the intended effects of the shampoo but it didn't make me feel itchy afterwards. I also felt it didn't strip my hair's moisture either and it felt clean after use. The scent also didn't bother me too much.
