Reasons for Hair Growth Rates to Change

Numerous reasons account for changes in the rate your hair grows. Sometimes hair growth increases and a tremendous growth spurt ensues; other times, the growth pattern has irreversibly stalled. According to the Mayo Clinic, "Due to hormonal changes, irritation or damage, some hair follicles have a shorter growth phase and produce thinner and shorter hair shafts. Your hair goes through a cycle of growth and rest. The course of each cycle varies by individual." Sudden and drastic changes in growth rate should be diagnosed by a physician.

Diet

• You are what you eat.

  If your diet has changed dramatically, it may affect the growth rate of your hair. Dermatologist Dr. Paradi Mirmiran says, "Losing a significant amount of weight in a short amount of time can affect that normal hair rhythm. Two to three months later, you might notice a significant increase in shedding. This is a temporary problem that you recover from with a well-rounded diet."

Age

• Bodily functions slow as we age.

  Aging usually causes a change in hair growth rate. It is common for men to experience some degree of balding. Women typically experience a slower growth rate and thinning hair, particularly during menopause. The best remedy is to eat, rest and exercise properly to fortify the body with the necessary nutrients. Supplements may help replenish nutrients and enzymes that your body no longer manufactures.

Medications

• Medications cause chemical changes.

  Just as a change in a diet can affect hair growth, so do some medications. According to Family Doctor.org, "Medicines that can cause hair loss include blood thinners, medicines used for gout, high blood pressure or heart problems, too much vitamin A, birth control pills and antidepressants." Conversely, certain medications can speed up the growth cycle of hair. Direct your serious concerns to a healthcare provider.

Hair Styling Processes

• Hair styling processes can affect growth.

  Harsh chemicals and overprocessing of the hair cannot only take a toll on your hair; they often affect the hair follicle. Damage to the follicle may retard the growth of your hair or stop growth completely. Hair and scalp trauma can result in permanent hair loss or stunted hair growth. Hair dryers can produce heat as high as 250 degrees Fahrenheit, which has the potential to cause damage to the hair follicle. Other causes of follicle damage include chemicals, friction, tight braids and even sunburn
