Jane: “It felt so nice to finally wash my hair, this was a rough challenge (but sort of fun, I’ll admit). I don’t think I’ll ever do this to this extent again, although now I feel more comfortable skipping a few days between washes. And no one even noticed that my hair was dirtier than usual, some even commented on how shiny and healthy it looked (since I wasn’t heat styling as often, I guess).

I would recommend this challenge to someone who is super busy or just plain lazy (I’ve been there too, so no judgement here). If you’re way too tired to wash your hair at night or you wake up late for work the next morning, then this is the way to go.

Molly: “It feels good knowing that I can go seven days without washing my hair (not that I would probably ever do this again, unless I got stranded on a desert island or something…) Nonetheless, it brings me relief to know that when I’m traveling or if I go camping and don’t have access to a shower for a few days, then all I really need is some dry shampoo to extend that blowout.

I would recommend the dirty hair challenge to someone who’s going a vacation with their sig-o. Not having to wash your hair makes your get-ready-time that much faster, so your man won’t have to wait around for you while you wash and dry your hair (which he’ll totally appreciate).”
