Revitalash, the eyelash growth product made by Athena, is launching a product for thinning hair that will be in salons and spas in February.

Hair by RevitaLash is based on many of the same ingredients as the eyelash conditioning product. So the obvious question is whether this will contain the prostaglandin (glaucoma drug) that is the active ingredient that makes eyelashes grow like weeds.

The product is a foam that is to be massaged into the scalp wherever hair is thinning. Athena says pre-market test results show noticeable improvements in two weeks.

Also look out for Latisse by the makers of Botox, Allergan, at the end of this month. This eyelash growth product has been approved by the FDA and contains the drug bimatoprost (0.03% ). Bimatoprost is a glaucoma drug. The US National Library of Medicine outlines these possible side effects from bimatoprost (when used to treat glaucoma):

"Bimatoprost may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

* itchy eyes
* dry eyes
* burning eyes
* eye pain or irritation
* eye tearing
* headaches

Some side effects can be serious. The following symptoms are uncommon, but if you experience any of them, call your doctor immediately:

* sensitivity to light
* pink eye
* redness or swelling of the eyelid

Bimatoprost may change the color of your eye (to brown) and darken the skin around the eye. It may also cause your eyelashes to grow longer and thicker and darken in color. These changes usually occur slowly, but they may be permanent."
