Shaving one's head can lead to increased risks of sunburn and skin cancer due to greater exposure of the scalp to sunlight. Individuals with different skin types have varying sensitivities to sun exposure, and while some may not burn easily, cumulative sun exposure can still pose a risk for skin cancer. It's suggested that wearing sunscreen or protective hats can mitigate these risks. Concerns about other potential issues, such as increased susceptibility to cold or wind, are also noted, but the primary focus remains on sun exposure. Regular use of sunscreen and protective measures is recommended, regardless of skin type, to prevent skin damage and associated health risks.
