Matrix SoColor Permanent Hair Colour Ultra-Blondes UL-A+ 90ml

Matrix SoColor Ultra-Blondes UL-A+ in 90ml is the proper professional choice for colourists wanting genuinely cool, ash-toned high-lift blonde results without the warmth, brassiness, or yellow that lesser high-lift colours leave behind. The UL-A+ shade delivers Ash Plus tone with extra neutralising power for stubborn warm undertones, properly suited to clients with darker natural bases who want to lift to cool blonde in a single colour service. Now with the upgraded pre-bonded complex featuring citric acid and glycine, plus naturally derived oil, this formula delivers up to 2x softer hair and up to 2x more shine after one use, all whilst protecting the integrity of the bonds inside the hair shaft.

Why Matrix SoColor Ultra-Blondes UL-A+ stands out

The Ultra-Blondes range is engineered specifically for high-lift colour services, properly capable of lifting natural hair up to 4-5 levels in a single application. Where most permanent colours top out at 2-3 levels of lift, Ultra-Blondes pushes further whilst maintaining the bond-protecting credentials that have made SoColor a salon trade favourite. The UL-A+ Ash Plus shade is the colourist's go-to when neutralising warm undertones matters most, brilliant for clients with darker natural hair who want to achieve cool, ashy blonde without the yellow or orange cast that high-lift colours can sometimes pull.

The upgraded pre-bonded complex explained

The latest SoColor formula has been upgraded with a pre-bonded complex of citric acid and glycine, properly engineered to protect the hair's internal bonds during the colouring process. This means no need for separate bonding additives like Olaplex No.1, K18 Mist, or Wella WellaPlex during the colour service, the bond protection is built into the formula itself. The result is hair that comes out of the colour service with visible improvement in condition, softness, and shine, alongside the colour result.

4. Bond protection: No additional bonding additive required, the upgraded pre-bonded complex is built into the formula

Important professional notes

Matrix SoColor Ultra-Blondes is a professional-use product designed for trained colourists. Always perform a 48-hour skin sensitivity test before colour application as per manufacturer guidelines. Wear protective gloves throughout application. For high-lift services on previously coloured hair, an alternative approach (such as a colour removal step or pre-lightener) may be required to achieve the desired result, properly trained colourists will assess this case by case.
