What Is Lanugo?

If a tumor causes lanugo, your healthcare provider will typically remove the tumor. Even if the tumor isn’t cancerous, it can rupture or lead to other problems. If your tumor is cancerous, your healthcare provider may recommend chemotherapy, radiation therapy or a combination of the two in addition to surgical removal. Once the tumor is treated, the lanugo hair should stop growing. Useful as lanugo may be in utero, it may not be a thing you want to highlight in your newborn baby’s photo session. Your newborn will likely be lanugo-free within a few weeks after birth.

The sight of a baby covered in hair can be distressing, but it is perfectly normal. Not all babies are born with lanugo, but all of them were coated with it in the womb. The hair usually goes away before birth, but sometimes it sticks around until a baby is born or even for a few months after.
How do you treat lanugo on an adult?
This is not lanugo and may be caused by a condition called spina bifida. Lanugo can occasionally regrow in older children or adults. However, this is a bigger mystery and might signify a more serious health issue. Premature babies tend to have more lanugo when they’re born. Although some full-term babies still have some left by the time they’re born, most shed this hair inside the womb before the eighth month.
Lanugo: What You Should Know
Blood tests can be useful to identify abnormal testosterone levels or other hormonal imbalances. If a doctor suspects an underlying health condition like thyroid disease or cancer, imaging tests like ultrasounds may be necessary. Pelvic and transvaginal ultrasounds can be helpful if looking for signs of PCOS, which is a common cause of hirsutism.
Most fetuses develop lanugo around the fourth or fifth month of pregnancy. But the hair is usually not present by the time of birth. Lanugo is the hair that covers the body of some newborns. This downy, unpigmented hair is the first type of hair that grows from hair follicles. It can be found everywhere on a baby’s body, except on the palms, lips, and soles of the feet. However, people with eating disorders or certain tumors or cancers can grow lanugo.
In disease states such as malnutrition and anorexia nervosa, where thermoregulation becomes disrupted, lanugo grows to help insulate the body. This growth is a natural response to an unnatural insult. Lanugo hair is important as it helps to hold the vernix caseosa, a protective layer, on a baby’s skin.
About 30% of all full-term babies are born with some lanugo. If your baby is born premature (before 37 weeks), they have a greater chance of having lanugo. It may take several weeks to go away, but lanugo will fall off on its own. Both conditions can trigger a nutritional deficiency and result in insufficient body fat. Lanugo grows as a physiological or natural response to insulate the body.
Lanugo and vellus hairs are similar in appearance, and it can be easy to confuse them. One theory is that the appearance of lanugo hairs on an adult is a result of the body trying to insulate itself and preserve heat. Scientists think this because lanugo often appears alongside conditions that reduce the body’s ability to control its own temperature, such as anorexia nervosa. Lanugo helps vernix (the waxy, cheese-like substance that covers the fetus) stick to the skin. Vernix helps protect a fetus’s body from amniotic fluid inside the uterus. Amniotic fluid could damage their delicate skin without lanugo and vernix.
Newborn Body Hair: Causes & Treatments for Lanugo
There are fewer than 50 documented cases of congenital hypertrichosis. It’s most common in men who live in India and Sri Lanka. It’s rare, but babies born to women with diabetes can have hairy ears. Studies show that the better you control your disease while you’re pregnant, the less likely your baby is to have it. Lanugo also helps to increase your baby’s growth rate around mid-gestation.
Another theory is that the movement of lanugo on your baby’s skin might play a role in the release of hormones that reduce stress and stimulate their growth inside the womb. As your baby gets closer to their due date (40 weeks), they will have less lanugo, less vernix, and less protection against the effects of floating in amniotic fluid. You can often see these effects when a baby is overdue, as they tend to have wrinkly, peeling skin. When it does, it is almost always due to advanced-stage eating disorders, particularly anorexia. Lanugo appears to play an essential role in the healthy development of a fetus. However, the appearance of lanugo on adults experiencing various diseases is a bit more mysterious.
If there is also a family history of similar symptoms, this can also help suggest the diagnosis. Some babies are born with a full head of hair, only to go bald within the first few months of life. Lanugo plays a vital role in binding the vernix to the skin; this protects the fetus from damaging substances found in amniotic fluid.
