Causes of a bald spot on the back of the head
Bald spot can arise from diverse factors, following are the common causes of a bald spot in the back,
Androgenetic Alopecia
Male or Female Pattern Baldness is a commonly used term to describe Androgenetic Alopecia.
It is the most frequent and common cause of hair loss.
Its causes include Genetic factors and hormonal imbalances that contribute to gradually thinning hair on the scalp, including the back of the head.
Alopecia Areata
Alopecia Areata is categorized as an autoimmune disorder, which results in hair loss in patches.
In an autoimmune disorder, the immune system mistakenly attacks the hair follicles which results in circular or irregular bald spots, including the back of the head.
Traction Alopecia
Traction Alopecia occurs due to constant pulling or tension on the hair follicles.
Hairstyles such as tight ponytails, braids, or buns can lead to hair breakage and bald spots, particularly at the back of the head.
Treatment options for a bald spot
The appropriate treatment options for a bald spot vary depending on the underlying cause of the hair loss.
Here are several commonly used approaches.
Topical Medications
Over-the-counter or prescription topical treatments containing Minoxidil help stimulate hair growth.
Minoxidil works by improving blood circulation to the hair follicles and prolonging the anagen (growth) phase of the hair cycle.
Oral Medications
Prescription medications like Finasteride are recommended for Androgenetic Alopecia.
Finasteride restricts the conversion of Testosterone to Dihydrotestosterone (DHT), a hormone responsible for hair loss.
Corticosteroid Injections
In cases of Alopecia Areata, corticosteroid injections can be administered directly into the affected area.
These injections help suppress the immune system’s attack on the hair follicles and promote regrowth.
Platelet-Rich Plasma (PRP) therapy
PRP therapy includes extracting a small amount of the patient’s blood.
It is then processed to concentrate the platelets and inject the platelet-rich plasma into the bald spot.
Platelets release growth factors that can stimulate hair follicles and promote growth.
Hair transplantation
Hair transplantation surgery is a procedure in which the transplantation is done by extracting hair follicles from a donor site and adding them to the area experiencing baldness.
This procedure suits individuals with permanent hair loss and can provide long-term, natural-looking results.
Lifestyle Changes
Avoiding tight hairstyles and reducing tension on the hair can prevent or slow down further hair loss.
Consuming a healthy diet is also necessary for overall well-being.
A stress-free and healthy lifestyle with a balanced diet, and should consist of the following.
- Protein-rich foods like poultry, fish, eggs, legumes, and nuts
- Consume iron-rich foods such as lean meats, seafood, spinach, and legumes
