Does Hair Dye Kill Lice or Nits?

Q: Someone told me that a strong permanent hair dye kills lice,  because ammonia in it. My hair stylist told me just to get hair dye with ammonia in it because it kills the lice. I’m not sure how true it is, but does it really work?

A: Hair Dye kills live lice but do not kill nits (lice eggs). Use it only as part of the 7-step process of ridding shampoo and lice:

  1. Identify nits hideouts: To kill lice, you must first find them. Adult female head louse lays eggs (nits) at the base of the hair, behind the ears and near the scalp. Lice and nits lice are almost exclusively on the scalp, particularly around and behind the ears and at the neckline at the back of the head.
  2. Remove the nit “glue”: Saturate the hair with vinegar for 1 hour and comb thoroughly first destroy the glue that head lice nits on the hair to fix with.
  3. Comb on the nits with a comb nit: Make-combs electronic combs, which are used on dry hair when shock and kill lice (not nits or eggs or lice really small). Although the hair dye can kill live lice, combing nits will still be needed first. Lice comb specific sessions NOT lice combing until the head or rivets were present on the comb lice comb at the end of the second session of head lice. You can also add Listerine to the point and barb these issues are annoying enough lice to find another home!
  4. Apply your favorite hair dye: The only way to really see if the hair dye kill lice is to try it yourself. The chemicals in hair dye can kill living worms, but it is not an effective way to treat lice. It is best to apply to a small area of ​​hair and wash your research first in order to verify compliance or wait until the natural dye does not wash prior to treatment. Dip dye her hair by dipping the tip in the dye, including dye with aluminum foil, waiting 45 minutes rinse hair.
  5. Optionally, apply lice and nit shampoo: Common lice shampoo to kill the lice bugs poisoning, suffocating lice or manual removal of lice. Lice generally be effectively treated with liquid or aerosol for killing lice or wet combing, using a specially designed lice comb (see above).
  6. Then use heat to kill the remaining lice: washing machine, bed-wetting or drying items at a temperature higher than 130 ° C can kill both lice and nits in your car and home. The heat kills the lice and nits dry before their colonization. The combination of these two methods of hair dye chemicals and heat from the dryer to kill all the bugs and nits. It must be repeated several times, because it does not kill the eggs.
  7. Retreat Your Hair: Always treat the head again 7-10 days after the first treatment to kill lice that hatched after the first treatment. You will need to do this several times, so kill lice that any new vulnerabilities.

If you decide to go with a method of hair dying, choose a product that is high in ammonia dye:

Henna hair dye – 23% ammonia

Henna is known to form a dye that is normal and hair dye is widely known plastic range of the dye. Henna can be used to color the hair, and has chemicals to restore healthy hair and skin.

Fenugreek seed powder has been shown to be highly effective against lice when mixed with henna body art quality and applied to the hair as henna dye.

Use only certified laboratory in pure Body art quality henna (high dye content, with no impurities or adulterants). The original neutral henna products not only kill and remove lice, but it can also be very effective in treating dandruff and even believed to strengthen the hair.

Even with the achievements of dyes, irritation of the scalp is still possible. Please note that some permanent hair dye products contain derivatives of aspirin, so it is important they are not used on the hair of children. Although henna is generally safe, consult your doctor before using henna on a child under the age of 12 in order to determine whether a child has G6PD deficiency.

HEDRIN hair dye – 10% ammonia

Instead of using insecticides to poison lice products HEDRIN kill them physically. The active ingredients to kill lice shampoo, and penetrate the eggs that hatch. You get used to these points while you are using tea tree oil to treat head lice for safe and naturally healthy hair.

Generic Hair dyes – Variable% ammonia

Over the counter (OTC) and prescription products can eliminate the lice, but it does not kill nits. The only thing, which is to help loosen the glue is the highly acidic Head and Shoulders. This will kill lice and perhaps some of the eggs / nits. You can also use a mixture of coal tar shampoo such as Nutragena or generic brands.

Tip: You can also buy tea tree oil and add it to your own shampoo and conditioner. The majority of lice treatments require the use seconds after approximately 10 days to kill lice which may be interrupted by initial treatment.

Why hair dye Kills Nits

Hair dye contains polyphenols, which in high concentrations penetrates the delicate exoskeletons  of Bugs, killing them as an insecticide. The high pH and strong chemicals, including alcohol contained in the dye can effectively and economically killing lice eggs.

However, this does not mean that you can go ahead and dye your hair, or your kid to get rid of lice, because the dye will not kill lice, but the nits, which have a much thicker outer shell. Nits are not fully developed neurological system, so it can affect the chemicals in hair dyes, and chemical substances can not penetrate the shell rivet.

Hair dye will kill the lice problem, but once nits hatch in 7-10 days, you’ll be exactly where it started.

Personally, I try to use hair dye to remove lice, but the results were far from satisfactory level.
