No. 3 Hair Perfector

The final stage of the much-lauded treatment that miraculously rebuilds broken bonds within chemically treated hair, this treatment is applied to damp hair and left on for a minimum of 10 minutes. Once dried you’ll notice the difference immediately: hair feels stronger, softer and like it has more internal weight (which is a good thing, trust us). The only hitch is you’ll need to try it with the rest of the system to get the full effect, but when it’s as loved by so many A-listers as this is, that’s not really a problem. 

This was definitely the best of the ones I tested – my hair felt like it did when I leave the salon and the effects lasted for a few washes.
