It is conceivable for a full-term baby to have lanugo at delivery, but the likelihood of this happening is minimal. After a few weeks, the lanugo should have shed completely. Lanugo begins to show up on your baby's skin around the fourth or fifth month of your pregnancy (by about 16 to 20 weeks gestation). At approximately 28 weeks, the lanugo is at its most abundant. After this point, a baby's layer of lanugo usually starts to shed.
Newborn Body Hair: Causes & Treatments for Lanugo
This may lead to a damaged spinal cord and nearby nerves, causing different disabilities. Lanugo might be light or have no color in babies with lighter skin. Babies with darker complexions tend to have darker hair and, therefore, darker lanugo. The dark color of the hair may make it more noticeable. More effort may go into finding the cause and appropriate course of treatment in cases of acquired hypertrichosis. Researchers aren’t exactly sure why and how the various forms of hypertrichosis occur, but there have been several studies exploring the possibility of a genetic cause.
Is it normal to have a hairy newborn?
Shortly after birth, a child will lose their lanugo and vellus hairs will replace them. These hairs are also fine and will last throughout the person’s life. It is natural for babies to be covered in lanugo, especially if they were born prematurely. However, the reappearance of lanugo in adults is unnatural and a sign of various health conditions.
Pictures of lanugo
Unborn babies develop lanugo between 16 to 20 weeks gestation. It covers their entire body except for places without hair follicles. Areas without hair follicles include their lips, palms, nails, genitals and soles of the feet.
Lanugo Hair – What is it?
The lanugo is a hair that covers the body of babies during pregnancy. It works as a protective later against infections, also helping to keep the fetus warm, as its skin is still very thin and lacks subcutaneous fat. Since they’re born before completing the typical gestation period, they might still have this protective layer of hair, which usually sheds before full-term birth. When lanugo regrows on adults, it’s often confused with thin vellus hair. However, one way to check this is by examining the person’s overall health and the hair’s location.

Why Would an Adult or Teenager Have Lanugo?
Doctors don’t know exactly why some people have so much. For many years, researchers thought it was a trait men passed down genetically, through their Y chromosome. Your baby might also acquire a bald spot on the back of their head. This spot usually results from spending a lot of time sleeping on their back. It is not intended to provide medical, legal, or any other professional advice. Any information here should not be considered absolutely correct, complete, and up-to-date.
What is Lanugo?
The first thing that needs to be done to treat anorexia, bulimia, or any other type of eating disorder is to receive professional assistance. In underweight people, lanugo grows as a protective strategy to help them keep their body temperature stable. Lanugo in adults and children might develop due to an eating disorder. Experts believe this may occur because their body has problems sustaining heat. The development of lanugo anorexia nervosa is frightful.
The lanugo hair will be replaced by short, low-pigmented markless vellus hair. If the clinician recognizes the presence of lanugo in a newborn, it should raise suspicion for prematurity; however, this is more often a normal variant than not. When lanugo is present in an adult, this is a “red flag,” and an underlying systemic disease should be investigated and ruled out.
Hypertrichosis vs. Hirsutism
If you have an eating disorder, seek help from your doctor. If you know someone with an eating disorder, encourage them to seek help. Gently massaging a baby’s skin after birth can facilitate the removal of lanugo. Although massaging can be effective, it isn’t without risks. A baby’s skin is delicate, and if you inadvertently rub your baby’s skin too hard or too much, this can cause soreness, redness, or dryness. Therefore, it may be more beneficial to leave the hair alone and allow it to shed on its own.
When there isn’t enough body fat, the body can’t stay warm. A baby’s skin is covered with a waxy, cheese-like substance called vernix, which protects the skin from amniotic fluid. Vernix prevents a baby’s skin from chaffing in the womb. Lanugo helps protect the skin and makes it easier for vernix to adhere to a baby’s skin. You’re probably used to seeing longer strands of terminal hair and short strands of vellus hair on your body.

The reviewers described it as the only case of such an association reported in the literature. A 2007 study reported that a person with prostate cancer developed lanugo-like hairs while experiencing the condition, but the hairs disappeared after treatment. Throughout the pregnancy, babies grow and develop in a sac filled with amniotic fluid. People who have widespread hypertrichosis may need to use more than one hair removal method. They may also need to use them repeatedly for treatment to be effective. The hair on one area of the body may not be removed well—or safely—using certain methods.
Beginning after the seventh or eighth month of pregnancy, there will typically be progressively less and less of the hair until it all disappears. Your baby does not start to put on significant weight or develop a layer of fat to keep them warm until the last few months of pregnancy. The growth of lanugo is believed to play a role in helping them regulate temperature, hold in heat, and keep warm inside the womb. The growth of lanugo in adults is thought to be an attempt by the body to warm itself in response to conditions that negatively affect body temperature.
Lanugo plays an essential role in binding the vernix caseosa to the skin of fetuses. It protects the fetus from damaging substances found in amniotic fluid, most notably urea and electrolytes.[1] Lanugo is the first type of hair to develop in humans. The interaction of lanugo with the vernix is also important in controlling the tempo of the fetal developmental rate during various times in the gestation cycle. Hair growth starts on the scalp around the eyebrow, nose, and forehead area and proceeds in a cephalocaudal direction from head to toe. It is shed at about 33 to 36 weeks gestation, when it becomes subsequently incorporated into the amniotic fluid, eventually contributing to the composition of the meconium. Lanugo is ultimately replaced by vellus (fine, thin hair) and terminal hair (thicker hairs found on the scalp, axilla, and genitalia).
For example, if your baby has darker skin, lanugo may be more visible than in a baby with fair skin. Once a baby sheds lanugo hair — either in the womb or outside the womb — the hair usually never returns. Electrolysis is the FDA-approved treatment for permanent hair removal. While the method does remove the hair permanently, electrolysis treatments can be painful and expensive.
