Follicle infection(Scalp Condition)-Hairline Loss Due To Sickness
Any inflammation or irritation of a hair follicle that presents as redness, pimples, pustules, itching or a rash on your scalp is called simple folliculitis, explains Callender. The most common is caused by tight hairstyles (traction alopecia), but the second most common irritation is allergic and sensitive reaction to chemicals in hair products such as chemical relaxers and even fragrances in shampoos and conditioners or styling products containing alcohol.
But even an infection caused by a buildup of sticky styling products not removed well enough attracts dirt and bacteria, which can plug pores and follicles, leading to serious secondary infections and hair loss. This infection needs effective treatment by a dermatologist in order to reverse any hair loss.
