A Beloved Lash Conditioner's Hair-Thickening Cousin

Fans of RevitaLash can rave endlessly about what it's done to increase the length and thickness of their eyelashes, but it's hard to empathize with them if the hairs you need to thicken are on top of your head. Luckily, the minds behind the popular eyelash conditioner have created Hair by RevitaLash.

Although it's called a hair conditioner, it's used much differently than the conditioners we're used to. After washing your hair, you apply one or two pumps directly to the areas where you're craving more fullness. Then, you don't rinse it out-you simply go forward with regular styling after letting it dry for a couple minutes.

When the formula is on your hair, it goes to work with seriously nourishing ingredients like ginkgo, ginseng, saw palmetto, wheat protein, panthenol and biotin to strengthen and enhance too-fine hair in just a few weeks.

Hair by RevitaLash isn't inexpensive, but neither is the original RevitaLash, and plenty of users say it's absolutely worth it.
