General symptoms
How to treat folliculitis decalvans
Treating folliculitis decalvans can be challenging due to its chronic nature, but various treatments can help manage symptoms, reduce inflammation, and prevent further hair loss.
Antibiotics
Creams may be applied directly to the affected areas to control bacterial infection. Long-term courses of oral antibiotics can also be used to reduce bacterial load and inflammation.
Anti-inflammatory medications
Medications such as Corticosteroids can be applied topically or injected directly into the scalp to reduce inflammation, with oral corticosteroids being used for short periods in severe cases.
Isotretinoin
In severe or resistant cases, low-dose isotretinoin may be prescribed with caution, as higher doses can inflame the condition.
Antibacterial shampoos
Regular use of antiseptic or antibacterial shampoos can help reduce bacteria buildup on the scalp.
Laser therapy
Laser treatments can be considered to destroy the hair follicles and stop the condition spreading or to switch off inflammation. We can refer you to a laser therapy specialist if required.
Hair transplantation
In cases where the disease is under control and scarring is stable, hair transplantation may be considered to restore hair in the affected areas. We can refer you to a hair transplant specialist if required.
Scalp reduction
In some cases, surgical removal of the scarred areas may be an option, though this is rare and only considered in severe cases.
How to prevent folliculitis decalvans
Preventing folliculitis decalvans can be challenging since the exact cause of the condition is not fully understood. However, there are some strategies that may help reduce the risk of developing the condition or prevent it from worsening if you are already affected:
- •Maintain good scalp hygiene
- •Avoid scalp irritation, especially through harsh hair products like dyes or bleaches
- •Manage skin conditions (such as acne or dermatitis)
- •Seek medical attention quickly if you notice abnormalities
