The Hair Boss Clear Shine Gloss (£15) is another product that's all about the shine rather than enhancing the tone or shade (if you choose the clear gloss, that is). The treatment, which comes in four shades, is almost like a preconditioning step.
For best results, the brand recommends to shampoo as normal, squeeze out excess water from your hair, apply the Clear Shine Gloss all over your hair making sure it's well saturated, and leave it to work for 20 minutes. Once the time is up, rinse the gloss out and follow with the deep condition mask provided, leave the mask to get to work, and rinse well. The process definitely isn't the quickest, but if you're looking to treat your hair to a deep condition, it'll result in an incredible shine.
