To all of you out there who suffer from dull, dry hair that no amount of serum, deep conditioner, or shine spray seems to fix: there is hope.

Yes, my friends, there is hope, and its name is Clairol Natural Instincts Shine Happy.

I had an opportunity to test out this little miracle a couple of weeks ago and am still delighting in its effects. Shine Happy is a treatment that revitalizes your hair with beautiful clear shine and silkiness, taking you from Bride of Frankenstein to Rapunzel in a matter of minutes. It's easy to use, the benefits last for an incredible four weeks, and it can be used on every hair type, whether natural, color-treated, highlighted, permed or relaxed. At only $7.99, it's one of those rare cheap thrills that really delivers.

The only (very minor) drawback is that it must be mixed with developer and applied with gloves, which could be daunting to home hair color novices. But fear not - the instructions are foolproof, and any apprehension will quickly evaporate when you dry your hair and reveal your gorgeous, shiny locks.

Since treating my hair with Shine Happy, it's shinier, softer, and more healthy looking - especially my highlights. It is shiny, and not just moderately so - I mean shiny in the manner of models in shampoo commercials. And people have noticed. The compliments alone have cemented my faith in this product, and now it shall be a staple in my hair care regime.

How else can $7.99 buy happiness?
