Revitalash Eyelash Conditioner, an eyelash growth product, is one helluva a successful product. The reason is simple: people who try it normally see results. I've never used it because I don't want to risk using a product that contains prostaglandins, a drug used to treat glaucoma. Nonetheless, Copley was game enough to give it a try and it worked for her too - lush lashes were reported and with no ill-effects. Now Revitalish has launched a new product for the hair and it will be fascinating to see if the company can extend its golden touch from lashes to locks.

Hair by Revitalash is a pricey $160. But then Revitalash Eyelash Conditioner isn't far behind. As a gratuitous aside, it amazes me that people balk at spending $150 on a good eye cream whilst having no price sensitivity to an eyelash growth product that costs $130.

Hair By Revitalash is a liquid that becomes a foam that can be rubbed into the scalp. It is supposed to result in thicker, fuller hair. Trading on the success of its eyelash product, Hair claims to have many of the same ingredients. And, indeed, it does contain our ol' frenemy (the ingredient listed as Trifluoromethyl Dechloro Ethylprostenolamide is the prostaglandin).

Now just because this tongue-twister works on eyelashes doesn't mean to say it will work on head hair. Actually it might. Recent research holds out much promise for the effect of prostaglandins on hair growth in general. Laboratory experiments with latanoprost (another variant on the glaucoma drug theme) have demonstrated stimulation of hair growth in mice and on the balding scalp of the stumptailed macaque.

The side-effects of prostaglandins - sore, itchy eyes, dark pigmentation of the skin where it is applied, change of eye color - may not apply to the head. So if you are concerned about looking like a stumptailed macaque, it may be worth giving Hair by Revitalash a try.
