Three weeks ago my son received a knock on his head bump came up which although not as painful now is still there and bald spot has appeared?

Possible Causes of Bald Spot:

- *Telogen Effluvium*: This temporary condition can cause hair thinning or bald spots due to stress or trauma to the body, such as a knock to the head.

- *Trichotillomania*: A hair-pulling disorder that might lead to bald patches.

- *Alopecia Areata*: An autoimmune condition that causes the body to attack its hair follicles, leading to bald spots.

- *Ringworm*: A fungal infection that can cause small, round, scaly, bald areas on the scalp.

- *Scarring alopecia*: Injury or trauma to the scalp can damage hair follicles, leading to scarring and permanent bald spots.

Recommendations:

Medical Consultation:

- If the bald spot persists, it's essential to consult a medical professional, such as a dermatologist, to determine the cause and receive appropriate treatment.

Observation:

- In some cases, bald spots can resolve on their own over time, particularly with Telogen Effluvium. Closely observe the area and note any changes.

Hair Growth:

- If it's a temporary hair loss condition, proper hair care practices like using gentle products and avoiding tight hairstyles can support hair growth.

Seek Medical Attention:

- If the bald spot worsens, becomes painful, develops unusual symptoms, or is causing significant distress, it's crucial to seek medical advice.

Avoid DIY Treatments:

- Consult with a healthcare professional before trying any DIY remedies to ensure safety and effectiveness.
