I couldn’t help but think about food and my eating game almost all day long. I would be in the middle of a dance or tennis match and be thinking of how much or little I would be able to eat for dinner. Even if I had wanted to begin focusing on the harm that I was causing my body rather than the number on the scale, I couldn’t seem to make myself. Hypertrichosis can have a detrimental effect on a person's social life. The anxiety may result in these children missing out on special events with their peers both at school and in the community, such as birthday parties and team sports. People who have the congenital form may have endured many years of bullying by their peers.
Lanugo hair
The clinician should note the degree of lanugo presence and its distribution as well, as this can correlate with disease severity. Nonetheless, most of the babies loss the lanugo during the 40th week of pregnancy. This, in turn, helps the vernix fulfill its purpose of protecting your baby’s skin from the amniotic fluid.
Congenital Hypertrichosis
However, it is not common or healthy for adults to have Lanugo hair…that doesn’t mean it doesn’t happen. It actually isn’t unusual to see the hair grow on anorexics who lose to much weight and are approaching emaciation. The hair grows on anorexic’s arms, chests, and backs as a way of self insulation. There is no cure for hypertrichosis, but knowing whether it's congenital or acquired can help doctors choose a treatment. If abnormal hair growth is due to another condition, managing the underlying medical disorder is the first-line treatment.

What is the purpose of lanugo?
The hair just inside your ear works with earwax to keep dirt and debris away from your eardrum. Lanugo doesn’t bother your baby, but trying to remove it probably will. A running water environment offers numerous microhabitats for many types of animals. Eating disorders and malignancies have also been found to cause lanugo.

Lanugo is more prone to occur in infants delivered preterm (before 37 weeks). A few weeks may pass, and lanugo will finally shed on its own. When this happens, the lanugo is soon shed within a few weeks. Lanugo is replaced by another type of hair called vellus hair, which is thinner than the former. Lanugo hairs send vibrations through the vernix every time your baby moves.
What Is Lanugo?
Your family’s genetics will also play a role, making the hair lighter or darker. In this article, we examine the role of lanugo and why it might grow on adults. A person can either be born with the condition or acquire it later in life. Babies have an increased risk of being born with spina bifida if the mother ran a high fever during her pregnancy or took the drug valproic acid for epilepsy (4).
Babies drink that fluid—along with whatever else is floating in it. After the baby takes in the lanugo, it will make its way through their system and become part of their first poop (meconium). Lanugo is the first hair that grows out of your baby’s hair follicles while they are still developing in the womb. The same review lists the growth of lanugo-like hairs as the second most common skin symptom to occur due to starvation in people experiencing anorexia. Lanugo is a type of fine hair that grows on the bodies of human fetuses while they are developing in the womb. However, babies may still have fine, peach-fuzz-like hair on the tops of the ears, above their tailbone or at the base of their neck.

Babies typically shed lanugo before birth; however, some babies don’t shed it for several weeks after birth. Lanugo on a baby’s skin isn’t a cause for concern, but if you have questions, don’t be afraid to speak with your doctor. The presence of lanugo on adult skin often points to an eating disorder and shouldn’t be ignored.
But these aren’t the only types of hair common to humans. Young people with hypertrichosis and their families can benefit from medical, social, and mental health resources. People with severe hypertrichosis may find it difficult, overwhelming, expensive, and painful to have abnormal hair growth routinely plucked, shaved, bleached, or waxed. Even for people who do not have abnormal hair growth, these measures are only temporary. If the abnormal hair growth is severe and begins in childhood, a diagnosis of congenital hypertrichosis is fairly simple.
Treating lanugo in adults involves treating the underlying condition. In the case of anorexia, bulimia or other eating disorder, getting help to treat these conditions is the first step. Lanugo develops as a defense mechanism in people who are underweight to maintain body temperature.
In this case, the lanugo mixes with amniotic fluid and gets swallowed by your baby. However, some babies are born with lanugo, especially if they are born before 37 weeks gestation (premature). If your baby is born with lanugo hair, it will go away on its own over time. Lanugo is one of the side effects of anorexia nervosa, bulimia nervosa and other eating disorders in adults. Healthcare providers believe lanugo grows when a person doesn’t have enough body fat to keep them warm. In response, their body grows lanugo to help insulate the body.
You might be able to see and feel lanugo on your baby’s back, shoulders, arms, forehead, and cheeks. It can occur in just a few spots or coat most of the body. As lanugo is not a health condition itself, it does not require treatment directly. Adult lanugo will naturally disappear when the condition triggering it, such as anorexia, is effectively treated.
Most fetuses develop lanugo around the fourth or fifth month of pregnancy and it has many important purposes for babies in the womb. However, the hair is usually not present by the time of birth. It often sheds around the seventh or eighth month of pregnancy, although it can linger and shed weeks after birth. If you’ve ever held a newborn baby, you may have noticed a layer of soft, downy hair over their body. This hair, known as lanugo, usually goes away within a couple of weeks. But lanugo can also show up in adults, especially those with eating disorders.
