What you should know about head lice and hair color

Fawn’s Fervent About Head Lice:

I was wondering if it is safe to put commercial lice treatment shampoos, Rid or Licex, on newly dyed hair. How long should you wait after treatment to dye your hair? Also, does the dye provide any lice protection?

The Left Brain Is Picky About Nits:

Thanks for your questions, Fawn. Hopefully these answers will help:

1) Without going into a lot of hair dye history, let’s just say that you should avoid using ANY shampoo on freshly dyed hair. That’s because the washing process removes a lot of dye. If you can, wait at least a couple of days before you shampoo.

2) You can have your hair dyed the next day after lice treatment. The active ingredients will essentially be washed away when you shampoo again. And even if a little is left behind, that shouldn’t interfere with the dying process.

3) While the dye itself won’t keep lice away AFTER you color, if there are any on your hair during the coloring process the high pH should scare the little buggers away.

    Ok, my question is: Can you dye your hair AFTER you’ve gotten rid of lice in the same day?

    Is lice shampoo going to strip the hair color I already have on my hair? It was dyed 2 weeks ago.

      I’m not aware of any interaction of lice shampoo with hair color so it should be fine. Even if your color faded a little bit wouldn’t it be worth it to deal with the lice problem?

      I also used Melathion (Ovide) and am wondering if I can dye my hair. I know it’s super flammable and potent!

    I just dyed my hair can I do a lice treatment two days after it got dyed, like is it going to fall out?

    • Perry Romanowski October 28, 2019, 9:49 am

      There shouldn’t be a problem treating hair for lice even after you colored it. It might negative affect the dye color but perhaps not.

    Hi! So I just dyed my hair Friday at 6 PM. It is now Sunday at 8:45 AM. I tried the natural remedies to get rid of the nits and one louse I saw and it didn’t work so I have to try the chemicals now. I just paid a lot of money for my hair and just really wanna know if anyone has had experience with the chemicals of the lice shampoo stripping the color off of you hair (it’s been less than 48 hours since I got it done). Thanks!
