Shhh... don't tell anyone but my wife uses hair colourant.
Clairol have been advertising on TV a product called nice'n easy colour blend foam. The advert made it look easy to use and I'm the one who gets to apply it so we gave it a go. Here's my opinion and you can probably tell from the title what it's going to be like.
First - it's NOT a foam. A foam is defined as a colloidal suspension of gas in a liquid. In other words it's thick and creamy with very small bubbles. Think shaving cream or spray cream - they are foams but Clairol nice'n easy is a FROTH - much bigger bubbles, think of the froth you see sometimes under a waterfall or the froth on top of a bubble bath.
Second - it's NOT easy. In fact it's the hardest colourant to apply I ever used. It runs. It fails to wet long hair. it's far too easy to get on skin and clothes.
Third - the results are poor. There's not enough 'froth' to cover hair as long as that in the picture on the box. Added to that the colour isn't as deep as it's made out to be.
Maybe if you have very short hair this stuff might be OK but we will NEVER buy this rubbish again. Back to the drawing board Clairol!
