Know the reasons for Hairloss and 7 Tips to Prevent HairLoss By Dermatologist
Causes and Types of Hairloss
1. Androgenetic alopecia:
- Both male and female pattern baldness is genetic. Males tend to lose hair from the temples and crown of the head. In females, hair usually becomes thinner all over the head.
- Androgenetic alopecia is more likely to happen as a person ages but can start at any point after puberty. Many females who experience androgenetic alopecia develop it after going through the menopause.
Telogen effluvium is a condition where the hair remains in the telogen (natural shedding) phase of the growth cycle. This causes more hair to fall out, sometimes in handfuls. It is temporary and the main causes are:
- severe stress
- thyroid problems
- rapid weight loss
- certain medications
Anagen effluvium causes large amounts of hair to fall out rapidly during the anagen (growth) phase of the hair cycle. This may cause hair to fall out from the head, as well as from other parts of the body, including eyebrows and eyelashes.
Causes of anagen effluvium include:
- fungal infections
- autoimmune disease: (complex and hard-to-treat immune system-related diseases. They occur when the immune system attacks healthy cells in the body. )
4. Traction alopecia
Traction alopecia is hair loss due to pulling hair into tight hairstyles, which causes it to break and come loose. Hairstyles associated with this condition include:
- tight buns or ponytails
Certain medications have side effects that can cause hair to fall out.
Examples of such medications include:
- blood thinners, such as warfarin
- Accutane, to treat acne
- antidepressants, including Prozac and Zoloft
- cholesterol-lowering drugs, such as Lopid
Nutritional deficiencies can cause hair to fall out. Extreme diets that are too low in protein and certain vitamins, such as iron, can sometimes cause excessive hair shedding.
7. Birth control pills
People may experience hair loss while using birth control pills. Others might experience hair loss several weeks or months after they stop taking them.8
Ringworm is a fungal infection that can cause hair loss. Ringworm on the scalp, or tinea capitis, can cause temporary bald areas on the head.
- a small spot that gets bigger, causing scaly, bald patches of skin
- brittle hair that breaks easily
- itchy, red patches of skin in the affected areas
- oozing blisters on the scalp
- ring-like patches, with a red outside and the inside of the circle matching the skin tone
Consult a Doctor if you are having any of these symptoms
Prevention of Hair loss
Most baldness is caused by genetics (male-pattern baldness and female-pattern baldness). This type of hair loss is not preventable.
These tips may help you avoid preventable types of hair loss:
- Avoid tight hairstyles, such as braids, buns or ponytails.
- Avoid compulsively twisting, rubbing or pulling your hair.
- Treat your hair gently when washing and brushing. A wide-toothed comb may help prevent pulling out hair.
- Avoid harsh treatments such as hot rollers, curling irons, hot oil treatments and permanents.
- Avoid medications and supplements that could cause hair loss.
- Protect your hair from sunlight and other sources of ultraviolet light.
- Stop smoking. Some studies show an association between smoking and baldness in men.
