My hair is pretty thin, slightly dry, and definitely looking lackluster lately, so I've taken up to reading reviews on different strengthening and reparative deep conditioners. My best friend is a bleach blonde, and she's been raving about the Philip Kingsley Elasticizer for a few months now, so I borrowed hers so that we could compare notes.

There are a few things that make this conditioner different from others. It comes with a plastic cap so that the heat from the shower can work to activate the ingredients. Since it's highly concentrated, it spreads easily through your hair and leaves behind a lingering light, clean scent. Also, it contains SPF and is recommended for use once to twice a week (depending on the level of dryness of your hair).

It's easy to use. Just apply a generous amount to the roots and lengths of your hair, concentrating especially on your ends. Clip hair up and cover with the shower cap for ten minutes. Then rinse your hair thoroughly and shampoo and condition as usual.

I was really excited by the results. My hair felt softer, looked shinier, and was smoother — it looked like it chugged a can of Red Bull! My friend loves the way it brightens up her hair and takes away all of the yellow brassiness and even some of the frizz. The only downside is that unfortunately, the shower cap isn't re-usable. It got pretty gooey and even after I rinsed it out, it felt like there was a slimy film left over. Still, it delivered results, and at $5.50 for one treatment, I got my money's worth.
