Coarse Hair Symptoms

Hair comes in all lengths and colors and can be found all over the body. We are mammals, after all. However, particular aspects of our hair may warrant a closer look.

Each of our hairs is composed of protein strands and rooted in our skin. Every strand lives for two to seven years before falling out and being replaced. Much like the rest of our body, hair changes in thickness and color as we age [1].

Coarse hair has the largest diameter of all hair textures and contains the cortex, cuticle, and medulla. Maybe coarse hair is the norm for you, and you're already familiar with some over-the-counter products that can help manage it. But, if coarse hair appears where it was not before, it may be the sign of a medical condition.

And, since hair largely grows on the exterior of the body, symptoms are easy to spot.

Checking to see if any of the following apply will be beneficial in identifying if you have coarse hair:

  • Dry hair ends
  • Thick patches of hair
  • Hair that is rough or hard to the touch
  • Hair that is difficult to work with

Coarse hair on the head can be normal, hereditary, and, in many cases, desired. Hair product manufacturers specifically advertise products that add volume and thickness to hair, both of which are components of coarse hair.

Concern over coarse hair is typically minimal, however, when coarse hair begins to grow unexpectedly, other factors may be in play.

Coarse Hair Causes Overview

Most people have hair covering one or more parts of their body. In fact, hair growth on people occurs on all but a handful of places on the human body. If your normal hair is coarse, it is likely due to genetics. If your hair is not typically coarse, but coarse hairs are beginning to appear, there are several potential causes.

Hereditary coarse hair causes:

  • Family Tree: Your family background and ethnicity influence your hair texture in different ways.
  • Systemic Disease: Unusual hair texture may also result from inherited genetic syndromes.

Medical coarse hair causes:

  • Hormonal Imbalance: Over- or underproduction of several types of hormones has been known to cause the growth of coarse hair [2]. Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormone [3]. Pituitary Cushing's and tumors have also been linked to coarse hair symptoms.

Environmental coarse hair causes:

  • Medicinal: Several medicines have been linked to the growth of coarse hair including testosterone, DHEA, anabolic steroids, and Minoxidil [4].

Coarse Hair Treatments and Relief

If your coarse hair symptoms are sudden and you have other coinciding symptoms, then it may be time to call your doctor.

Consult your doctor if coarse hair is found in conjunction with:

If you are experiencing any of these symptoms along with coarse hair, it is recommended that you schedule an appointment with a physician. The conditions listed above do not lend themselves to home remedies. Over-the-counter pain medication may provide temporary relief, but only a doctor can determine if the symptoms are related and what the underlying cause may be [5].

Professional coarse hair treatments:

  • Prescription Medications: Your doctor may prescribe a variety of medications to help manage the growth of coarse hair.
  • Removal: Professional techniques such as electrolysis provide some form of temporary or permanent removal [6].
  • Surgery: Certain surgical procedures may be necessary if hormonal imbalances are the result of pituitary issues. A pituitary tumor causing coarse hair, among other things, requires surgical removal.

At-home coarse hair treatments:

  • Removal: Controlling coarse hair can be done through a variety of at-home treatment including shaving, chemicals, and waxing.
  • Hair products: A wide range of hair products designed to manage coarse hair on the head are available.

Oftentimes, coarse hair is unavoidable. Thyroid disorders and hormonal imbalances are treatable. If, however, your coarse hair is natural and expected, but difficult to manage, you may simply need one of the wide range of hair products that can help you have your hair looking and feeling its best.

FAQs About Coarse Hair

Here are some frequently asked questions about coarse hair.

Why has the texture of my hair changed?

As we age, our hair texture changes, but textural changes may also be the result of genetic syndromes or from the use of certain medications. Issues with the pituitary gland, for example, have been known to alter hair texture and the use of testosterone, anabolic steroids, and DHEA can change hair texture as well.

Can certain medications affect the coarseness of my hair?

Medications can affect hair in a variety of ways. The pituitary gland and the thyroid can play a significant role in hair texture, and medications for either can affect coarseness. Steroids and testosterone can also affect hair growth and texture.

How do I stop my hair from breaking off?

When hair is stripped of its natural oils it can become stiff and brittle. Conditioners can help moisten the hair and using softer brushes or combs will further limit damage. Adding combinations of cider vinegar and oils to hair can also help restore its strength.

Is coarse hair hereditary?

Genetics and ethnicity are both important factors in determining hair texture. Your hereditary may simply help define the coarseness of your hair or result in genetic disorders that can cause the coarseness to change.

Why is my pubic hair so coarse?

Pubic hair is typically developed during puberty as a result of increased levels of androgens in men and estrogen in women. The hair is often coarser in nature than hair found on the rest of the body. Coarse hair can also sometimes be a sign of genetic disorders or caused by certain medications.
