These bacteria enter the follicles through tiny cuts, shaving injuries, or irritation, causing inflammation and pus-filled bumps. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
- Fungal Infection
Yeast or fungi — particularly Malassezia — can overgrow on the scalp and infect hair follicles.
This usually happens in humid climates or when the scalp becomes excessively oily. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
- Viral Infection
Although less common, certain viral infections such as herpes simplex can cause follicular inflammation. This type usually presents with painful clusters of lesions. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
- Allergic Reactions
Scalp products like shampoos, hair dyes, gels, or conditioners can sometimes cause contact dermatitis, leading to inflamed and irritated follicles. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
Harsh chemicals, fragrances, or preservatives are frequent culprits.
- Hormonal Changes
Hormonal fluctuations can increase scalp oil production, especially during puberty, pregnancy, or stress.
Excess oil creates an environment where bacteria and fungi thrive, resulting in folliculitis.
- Excessive Sweating
Sweat buildup, especially after workouts or in hot weather, can clog hair follicles and attract bacteria.
Wearing helmets or caps for extended periods can worsen the issue. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
- Poor Scalp Hygiene
Not washing the scalp regularly or using heavy, oily products can block follicles and trigger inflammation.
This often leads to persistent itchiness and bumps.
- Ingrown Hairs
Tight hairstyles, shaving the head, or improper hair removal techniques can cause hairs to curl back into the skin, resulting in irritation and folliculitis. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
- Underlying Medical Conditions
Skin conditions like seborrheic dermatitis, acne, or eczema can make the scalp more prone to folliculitis.
People with weakened immune systems may experience repeated episodes. Best hair loss treatment in Varanasi: Dr. Shailesh Singh
When Should You See a Doctor?
If your symptoms don’t improve within a week, or if the bumps spread, become painful, or form crusts, it’s best to consult a dermatologist.
Timely treatment can prevent scarring and further infection.
