Hair Loss and Scalp Issues After Head Injury: What to Do? - Surgery

More Info

---

After a head injury, particularly one that results in a significant wound or trauma to the scalp, it is not uncommon to experience hair loss in the affected area. This can occur for several reasons, including damage to the hair follicles, inflammation, or the formation of scar tissue. In your brother's case, the presence of a "hole" in the scalp where hair has not regrown, along with the white appearance of the skin, suggests that there may be some underlying issues that need to be addressed.

When hair follicles are damaged due to trauma, they can enter a resting phase known as telogen effluvium, where hair falls out and does not regrow for a period of time. However, if the injury was severe enough to cause scarring (known as scarring alopecia), the hair follicles may be permanently damaged, leading to irreversible hair loss in that area. The white appearance you described could indicate the presence of scar tissue or a lack of pigmentation in the skin, which can occur after significant injury.

Given these concerns, it is advisable for your brother to see a dermatologist, a medical professional specializing in skin, hair, and nail disorders. A dermatologist can assess the affected area, determine the extent of the damage, and provide a diagnosis. They may perform a physical examination and possibly a biopsy if there is suspicion of scarring alopecia or other scalp conditions.
In terms of treatment, if the hair loss is due to scarring, options may be limited, but there are still some avenues to explore. Treatments such as corticosteroid injections can help reduce inflammation and promote healing in some cases. If the hair follicles are still viable, topical treatments like minoxidil may be recommended to stimulate hair growth. In cases of significant scarring, surgical options such as hair transplantation may be considered, although this is typically reserved for cases where there is a clear indication that hair follicles can be successfully transplanted.

It is also important to address any underlying issues that may contribute to hair loss, such as stress or nutritional deficiencies. Encouraging your brother to maintain a balanced diet rich in vitamins and minerals, particularly those known to support hair health (like biotin, zinc, and vitamins A and D), can be beneficial. Additionally, managing stress through relaxation techniques or counseling may help mitigate any further hair loss.

In summary, your brother should see a dermatologist for a thorough evaluation of the scalp injury and hair loss. Early intervention can be crucial in determining the best course of action and potentially restoring hair growth or managing the condition effectively.
