Customers generally appreciate the product's ability to preserve colour, add shine and luster, clean effectively and condition without heaviness, with many praising the original pleasant scent. However, feedback highlights inconsistent colour performance after a reformulation: uneven colour uptake, unwanted orange/yellow tones, and reports of a disliked new fragrance leading some pro users to consider switching brands. Pricing is also seen as high by professionals, and there is confusion around the product numbering and colour codes.
