peachVellus hair or “peach fuzz” is the soft, light hair that grows on our upper lip, cheeks, arms, legs, backs, you name it. Vellus hair develops during childhood and everyone has it. But as we reach puberty, some of the vellus hair then becomes “terminal” or adult hair, and for some people this terminal hair grows in unwanted locations.

Why do we even have this unnecessary hair when it doesn’t seem to serve a purpose?

Explained in an article called The Big Question: Why Does Hair Grow in Some Places But Not Others? posted on April 21, 2015 on the Wired magazine Science blog, vellus hair is an evolutionary relic. It doesn’t hurt anything, so it just hangs around.

For most people, it’s not a big deal. But for some, especially women, this hair can grow too much, causing much embarrassment and requiring a lot of time and emotional energy to manage.

If this is happening to you, first get checked out to be sure you’re not suffering from a condition like polycystic ovary syndrome (PCS), hormonal imbalance, pituitary tumor, or liver disease. Excess hair growth is a side effect of all these conditions.

So how do you get rid of vellus hair?

All of the traditional methods do work – waxing, shaving, plucking, threading, and dermaplaning – but they are also all temporary.

Medication like Vaniqa can slow down the growth of facial hair over time and reduce the amount of time you have to spend managing it, but requires 2x daily application over 4-8 weeks and isn’t permanent either.

Laser hair removal can also have a positive effect on dark hair, but is largely ineffective on blond or transparent hair. Lasers have the most impact of the above methods, but only the patented technology of the LP System from Lucy Peters can permanently remove hair forever.
