How Does Brow Hair Grow?

Hair grows from the follicles; it’s the living part of the hair. The visible part, the hair shaft, is made up of dead, hard protein called keratin, so once the hair strand structure is damaged it won’t regenerate (heal back) by itself.

 Average Brow Growth Rate

Eyebrow hair grows on a very short cycle compared to head hair. For eyebrows, the whole cycle is completed in around 4 months, while it takes the scalp 3–4 years to finish. This is why eyebrow hairs have a much shorter maximum length than the hair on your head.

 What Can Cause Severe Brow Hair Loss?

Certain drugs and medications can cause eyebrow hair to fall out. Eyebrows can begin growing about one or two months after the completion of using certain medications, but it could take up to six months for eyebrows to fully grow back. It’s also possible that the new hair will be thinner, a different color or a different texture.

 The Average Wait From Plucking

The hair follicle is a structure of the skin from which hair grows. There are hair follicles all over the skin, with the exception of the lips, palms of the hands, and soles of the feet. Hair follicles grow hair by packing old cells together.

 What Hair Is Made Of?

Keratin is the same tough, water insoluble structural material that human nails are made of. Hair also contains natural oils (lipids) and water. These hair components are arranged in 3 primary structures: the cuticle (which is the outermost, shingle-like layer); the cortex (the inside of the hair consisting of bundles of protein filaments, it helps to support the hair’s strength and also makes up the biggest portion of the hair); and the medulla (a soft spongy-like core in the center of the cortex.)

Why Are Eyebrows so Slow to Grow?

Eyebrows have a naturally much slower rate of regrowth than body or head hair. Hair growth is a cycle made up of several phases. The longer it takes the entire cycle to complete, the fast hair will grow during the early phases and the longer the final length can be. For the hair on your head, this cycle takes between 3 and 4 years on average, but eyebrows complete the same cycle in right around 4 months. This is why eyebrows seem to take so long to grow, and why eyebrow hair always remains so short.

Overall, the length of the growth phase and the width of the hair shaft are the results of your genes, and are not affected by anything you do to your skin or to the hair shaft itself. Depending on genetics, as most people age, their hair cycles can become shorter.

 Chemotherapy Brow Recovery

Hair loss after chemotherapy is a common occurrence and it happens as the chemotherapy targets not only the cancer cells but also the healthy cells of the body. However, once the chemotherapy is stopped your hair will need vital support to grow back to normal density and texture.
