Dry scalp itself doesn't directly cause hair loss, but it can contribute to hair thinning and loss indirectly. Scratching an itchy, dry scalp can injure hair follicles, leading to hair loss. Additionally, conditions often associated with dry scalps, like dandruff and seborrheic dermatitis, can exacerbate hair loss in some cases, particularly in individuals with androgenic alopecia (male or female pattern baldness).
How Dry Scalp Relates to Hair Loss
Several factors link dry scalp to hair loss:
- Physical Damage: Intense scratching from an itchy, dry scalp damages hair follicles. This damage hinders hair growth and can result in thinning or hair loss. [Reference: A dry, itchy scalp can not only be irritating and embarrassing but, scratching can injure your hair follicles, leading to thinning hair or hair loss.]
- Associated Conditions: Dry scalp often accompanies conditions like dandruff and seborrheic dermatitis. These conditions can cause inflammation and irritation, potentially contributing to hair loss. [Reference: There are certain ailments like Seborrheic Dermatitis and Scalp Psoriasis that can also lead to dry scaly patches. These can cause temporary hair loss on the]
- Exacerbation of Existing Conditions: While not a primary cause, a dry scalp can worsen existing hair loss conditions like androgenic alopecia. Dandruff, frequently associated with dry scalps, might increase hair loss in these cases. [Reference: In addition, dandruff can increase hair loss in some cases of androgenic alopecia, also called male or female-pattern baldness.]
- Underlying Conditions: Sometimes, dry scalp is a symptom of a more serious underlying condition like tinea capitis (a fungal infection). These conditions can cause hair loss if left untreated. [Reference: Tzu warns that tinea capitis can continue to spread across the scalp and cause additional hair loss if not stopped in its tracks.]
