Let's learn about this fine vellus hair or "Peach Fuzz" on your body.

Today we're going to talk about something that you may not have paid much attention to, but is very important. It's a fine hair called vellus hair . Some people also call it "peach fuzz" because it resembles the fine fur on a peach. So, today we're going to talk in detail about what these are, what they are for, and whether changes in them are a sign of any disease.

What is Vellus Hair? Simply put...

In most parts of your body, apart from the thick hair on your head (we call them terminal hair ), there is a very fine, thin, short type of hair, right? That's what we call vellus hair . These are usually very fine, in fact, sometimes so fine that they are not even visible. However, the length, thickness, and color of these vellus hairs can vary from person to person. It depends on things like your genetics, age, and hormone levels.

Imagine, that fine, soft hair that you can feel if you slowly run your hand along it... That's what vellus hair is.

These are completely different from the hair on your head. The hair on your head is thick, long, and dark. But vellus hair is not.

What are the benefits of these little bugs for our bodies?

"So what are these little things for?" you might be wondering. Don't be surprised, these little things do our bodies a great service.

• Regulating body temperature : Vellus hair acts as a small shield for our skin and helps retain body heat. Also, when we sweat, this hair helps to evaporate the sweat quickly and cool the body. This can then protect the body from overheating (heat illness).
• Skin protection: This delicate layer of sebum provides a little protection to the skin.
• Sensation : Just think, even if a slight breeze blows or a small animal like a mosquito bites our skin, it is because of these tiny hairs. Similarly, when we shiver on a cold day, when our skin gets goosebumps, it is because of these vellus hairs.

What is the difference between Vellus Hair and Terminal Hair?

As we said before, these two are very different. Terminal hair is:

• Thick, coarse hair.
• It grows long.
• Usually dark in color.
• These are mainly found on the head, armpits, face (beard, mustache) in boys (and some girls) after puberty, and in private areas.

Vellus hair is:

• Thin, delicate, short hair.
• Usually light in color, sometimes almost invisible.
• These are found in many places on the body.

Where is Vellus Hair found on our body?

In fact, we have vellus hair in many places on our bodies. For example:

• Arms, shoulders, legs, hips, buttocks
• Face, forehead, nose, earlobes
• Neck, chest, breasts , back, stomach, all over the body
• These can even be seen on the knuckles.

However, there are also places where this vellus hair is absent. These are:

• Alla (palms of your hands)
• Soles of your feet
• Lips
• Eyelids

What does vellus hair look like?

To many people, vellus hair is very fine, fine, and looks like a wisp of cotton. It is shorter and lighter in color than terminal hair. It can range in color from light yellow to dark brown. The appearance and amount of vellus hair you have depends on your genetics, age, and hormone levels . Vellus hair usually thins, becomes shorter, and may even fall out as you age. This is why children and young adults tend to have more vellus hair than adults.

What happens to vellus hair during puberty?

This is something that many people have experienced. When we say that changes occur "as we age," that's when these hormones start to play a role. In particular, our body's endocrine system starts to produce more hormones called androgens . Due to the increase in these androgens, the fine vellus hair in some parts of the body turns into thicker terminal hair .

• Vellus hair in the private areas and armpits turns into dark, thick terminal hair.
• In boys (and sometimes in girls who are going through puberty), the hair on the upper lip, where the beard grows, becomes darker and thicker.
• Also, the hair on boys' backs, chests, knuckles, arms, and legs begins to grow longer and thicker.

All this happens because that vellus hair transforms into terminal hair.

Conditions that may be associated with abnormal growth of vellus hair

Sometimes, an unusual change in the amount or appearance of these vellus hairs can be a sign of a health problem.

• Some medications: For example, chemotherapy for cancerMedications such as these can cause thick terminal hair to fall out, and sometimes they can turn into vellus hair. However, this condition often returns to normal after the medication is stopped.
• Cushing syndrome: In this condition, vellus hair can grow excessively on areas such as the face, neck, chest, abdomen, breasts, and legs.
• Eruptive vellus hair cysts : This is a rare abnormality that occurs in the hair follicles of vellus hair. This causes small red or brown blister-like cysts to form on the skin. They are most commonly seen on the chest, arms, and torso. This condition is more common in young people.
• Hirsutism: In this condition, women develop thick, dark-colored terminal hair-like hairs in areas where they normally have fine vellus hair (e.g., face, chest, back).
• Hypertrichosis: This is characterized by excessive growth of vellus hair all over the body. It can be caused by various medical conditions or certain medications.
• Male pattern baldness: In this, the androgen hormone dihydrotestosterone (DHT) damages the hair follicles. This damage causes the thick terminal hair on the scalp to gradually turn into fine vellus hair, eventually leading to hair loss and baldness. Hair loss in women can also be caused by changes in certain hormones.
• Eating disorders: People with conditions like anorexia nervosa and bulimia nervosa may develop a special type of hair called lanugo all over their bodies due to malnutrition. This lanugo is a hair that is slightly thicker than vellus hair, resembling cat fur. In fact, this lanugo hair develops while babies are in the womb and falls out a few days after birth.

So, if you suddenly notice an increase in vellus hair on your body, or if it feels thicker than usual, it's best to seek medical advice.

How do you remove this delicate peach fuzz?

There is no medical reason to remove normal vellus hair. They are beneficial to the body. However, for some people, the appearance of "peach fuzz" can be uncomfortable. For example, they may feel like makeup doesn't blend well with the skin. There are several ways to remove them. It's best to talk to a doctor to decide which method is best for you. Here are some of the main methods:

• Depilatory creams and shaving: These methods temporarily remove hair from the surface of the skin. Most importantly, if you are using a cream like this to remove hair from your face, make sure to choose a face-specific cream. Depilatory creams used on the body are harsher and can damage facial skin.
• Dermaplaning: This is a professional treatment that uses a special device to remove the top layer of dead skin cells, along with fine vellus hair.
• Electrolysis: This is a method that can permanently remove moles, but you will have to go through several sessions.
• Threading: This involves using two thin threads to first remove a few hairs at a time. This method is often used to shape the eyebrows and remove hairs above the upper lip.
• Waxing: This involves applying a hot, sticky wax to the skin, placing a strip of cloth over it, and pulling it away from the hair follicles.

Extremely important: Never, ever bleach vellus hair! Doing so can severely damage your skin and permanently change your skin color.

When this delicate peach fuzz is removed, does it come back thicker?

This is a question that many people ask, and it is also something that many people are afraid of. "Oh, if I shave or wax my hair, will it grow back thicker and more spiky?" The good news is, it doesn't! Vellus hair, or any other hair, does not grow back thicker after it is removed. When the top of the new hair comes out of the skin, its tip is a little blunt, so we can feel it as thicker. It's like when you sharpen a pencil and use it, the tip becomes blunt. But as the hair grows a little, that smoothness returns. So, there is nothing to worry about.

Final Take-Home Message

So, you probably now understand that the vellus hair , or "peach fuzz" we talked about today, is something that protects our skin, regulates body temperature, and, despite being small, does a big job.

• These are normal, they are present in everyone's body.
• If you don't like the look of your mole, there are ways to safely remove it. However, it's wise to talk to a doctor or a qualified cosmetic surgeon about which method is right for you, and whether you want to remove it temporarily or permanently.
• The most important thing is that if you suddenly notice an unusual increase in vellus hair on your body, or if it seems thicker than usual, or if you notice new hairs growing in places where there were none, don't ignore it. Be sure to see a doctor for advice. It could be a sign of another underlying medical condition.

So, take care of your body, because your body is your most valuable asset!
