What Are Head Lice?

Lice

Head lice refer to small insects that live on the scalp and thrive by feeding on the blood they retrieve by biting the scalp (1). In most cases, lice do not carry any diseases or germs; they simply cause irritation and itching by biting the scalp. The only cause of concern is that adult female lice attach themselves to the root of the hair and lay eggs there within 7 to 10 days of being born. Therefore, they multiply in no time and cause further discomfort.

It is extremely easy to contract a lice infestation, as it spreads via the slightest head-to-head contact in most cases. If lice infest a person, it is essential to ensure that she has no common combs, towels, hats, etc., to prevent the infestation from spreading. At the same time, the affected person may consider taking lice treatment. But, for pregnant women, this might not be an option. Read on to know more.

Why Lice in Hair Occur During Pregnancy?

Pregnancy itself does not cause head lice, but certain changes in daily routines and close contact with others can make an infestation more likely. Here are some common reasons lice may appear during pregnancy (2):

1. Close Contact With Someone Who Has Lice

Head lice spread mainly through direct hair-to-hair contact with an infested person. Spending time in close physical contact can increase the chance of transmission.

2. Sharing Personal Items

Using someone else’s combs, brushes, hair accessories, scarves, hats, or bedding may increase the risk of coming into contact with lice or their eggs.

3. Frequent Contact With Children

Pregnant women who regularly care for or spend time with children may have more opportunities for close head-to-head contact, which is a common way lice spread.

4. Previous Lice Exposure

If you or someone in your household has recently had head lice, there may be a higher chance of reinfestation, especially if bedding, combs, or other potentially affected items were not properly cleaned.

Is It Safe to Use Lice Treatment During Pregnancy?

After a woman is found to be pregnant, doctors advise her to check before consuming any medication. This is because the medicines have to be vetted and checked to find out if they harm the child. However, in the case of lice, women simply rush to the nearest medical store and ask for a lice treatment shampoo, often forgetting that the shampoo might contain harsh chemicals, which can adversely affect the health of the pregnant woman and the unborn child.

Let’s examine both options for treating head lice. The information below will help you decide to ensure your and your baby’s health is not compromised.

Head Lice Treatment During Pregnancy

Although we have provided information on medical treatment for lice below, it is not recommended as the chemicals could be harmful during pregnancy. However, try the natural means that suit you the most.

1. Medical Treatment

Consider treatment only when needed: During pregnancy, it is best to start with non-chemical methods, such as careful wet combing. If these methods do not clear the infestation, speak with your doctor about whether a medicated lice treatment is appropriate.
Ask about pregnancy-safe options: Some lice treatments may be suitable during pregnancy, but their safety can vary depending on the active ingredient and product formulation. A 4% dimethicone lotion is one option that may be recommended for pregnant or breastfeeding women. Always consult your healthcare provider before using it and check the product label for pregnancy warnings (3).
Follow the treatment instructions carefully: Some treatments may need to be repeated to target lice that hatch from eggs remaining after the first application. Follow the product instructions or your healthcare provider’s advice rather than applying the treatment more frequently than recommended.
Avoid self-medication: If lice continue after treatment, do not switch to another product or repeat applications without medical advice. Your doctor can recommend an appropriate next step and help you avoid unnecessary exposure to ingredients that may not be suitable during pregnancy.

2. Natural Ways to Treat Head Lice

These natural pregnancy safe lice treatments can treat head lice.

Tea tree oil in its pure form can get rid of lice without causing any harm to your fetus. You must mix a few drops of the oil in baby shampoo and apply it on your scalp while bathing. Depending on the extent of the infestation, massage it into the scalp. Let it stay for around half an hour, after which you can rinse your hair thoroughly. You can repeat this method as many times as needed.
Nitpicking is another excellent way to help you get rid of lice. First, divide the scalp into eight manageable areas, then comb each one thoroughly with a lice comb to eliminate as many lice as possible. Then, you can use your fingers for a more thorough search. Repeat this after a week to remove the lice from the hatched eggs.
Lavender, neem, eucalyptus, and clove oil are also great for combat lice infestation (4).
Wet combing can also help get rid of lice. After a thorough head wash, comb your hair (you may use a conditioner to smoothen the hair). Then, use a lice comb to remove as many head lice as possible (3). You can also part your hair in several sections and use your fingers to search through and clean the infestation.

When to Consult a Doctor?

If you have tried natural remedies and nothing has worked, you might have to consult the doctor to eliminate the lice infestation. Do mention that you are pregnant so that you get only the medication that is safe for you and the child growing inside your belly.
