5 Best Blue Shampoos for Brassy Hair 2025 – Tested & Reviewed

In daily testing, Matrix delivers visible results within a wash or two. Users with moderate brassiness see color improvement and less yellowing, especially when following the recommended leave-on protocol. The creamy lather is pleasant and doesn't strip hair, though some report minor staining on hands or shower surfaces.

Feedback is overwhelmingly positive regarding tone correction and scent, but split over post-wash feel: some love the softness, while others note slight dryness (more likely in bleached, porous hair). Consider following with a moisturizing conditioner, especially if your hair texture trends dry.

Day-to-day use is gentle and pleasant, with minimal scent and a smooth, creamy application. Hair feels stronger, not brittle, and toning occurs steadily over 2-3 washes. It avoids over-toning or dulling the hair, making it ideal for maintenance rather than major color correction.

There is limited feedback available about this Australian salon brand, but based on typical results, it suits those who want a gentle, consistent anti-brass routine.

When used after a blue shampoo, NAK Nourish leaves hair feeling noticeably softer and more manageable. The absence of heavy scent and the presence of rich lather make it a popular pick among users with scalp sensitivities. Moisture replenishment is evident after a week, and frizz is notably reduced.

Although not a direct anti-brass product, loyal users swear by it for creating a strong foundation for any coloring routine. Consider it a strategic pick for anyone following a two-shampoo system.

Fans love the way their hair feels silky and manageable with minimal product. It works especially well for those with naturally dry or overprocessed hair who want to alternate toning with non-pigmented formulas.

There's a split on whether the nourishing claims outweigh a slight risk of residue, especially if used daily on fine or oily hair. Those with chronically dry hair, however, see marked improvement in softness and shine.

Users rave about improved shine, a creamy lather, and the set's scent. Hair generally feels healthier and more manageable, especially for those following with the conditioner. There's praise for bringing life back to tired, brassy tones—plus a few reports of faster hair regrowth.

Some users with finer or drier hair notice dryness, especially with frequent use—mixing in deep conditioners will help avoid this. While a few customers found the results less dramatic than hoped, most appreciate the salon-like finish and peace of mind from the satisfaction guarantee.
