This shampoo is for people with grey, white, or lightened/bleached blonde hair who notice yellow or brassy undertones and want to correct them during a normal wash. It works on natural grey and white hair as well as color-treated blonde hair, and on any hair length. It's a straightforward, consumer-friendly wash-in, rinse-out product rather than a professional-only glaze or toner, so it doesn't require salon expertise to use.

What sets this shampoo apart is that it tackles yellowing through actual color correction rather than just cleansing — the violet pigment cancels out warm yellow tones the moment it touches hair, while the walnut leaf, rhatany root, and broom extracts are the same tannin-rich botanicals Phyto has historically built its color-correcting shampoos around. For anyone whose grey, white, or lightened hair keeps drifting yellow between salon visits, that means the correction happens as part of a normal wash rather than requiring a separate toning product.

Apply to wet hair, massage gently into a lather, and rinse thoroughly. Use it in place of a regular shampoo whenever hair needs de-yellowing.

Pros:

• The violet pigment corrects yellow/brassy tones through direct color neutralization rather than relying on fragrance or shine additives alone
• Works across a range of 'yellowing' hair types — natural grey, natural white, and lightened/bleached blonde
• Doubles as a regular cleanser, so no separate toning step is needed

Cons:

• Contains sodium laureth sulfate, a sulfate-based cleanser that can be more drying than sulfate-free purple shampoos
• Contains methylchloroisothiazolinone and methylisothiazolinone preservatives, which are recognized potential skin sensitizers for some users
• As with any pigmented purple shampoo, leaving it on too long or using it too often on very light or white hair risks an over-toned, ashy-purple cast
