lack of sunlight
Lack of sunlight not only causes vitamin D deficiency, but it can also affect your sleep and worsen hair loss.
“Less daylight hours in winter means less exposure to natural sunlight, which can disrupt these cycles and worsen hair loss,” says Phil. “To combat this, try spending more time outdoors during the day or using light therapy to mimic the effects of natural sunlight.”
cold climate
Cold temperatures can slow blood flow to your body, including your scalp.
“Cold temperatures can reduce blood circulation to the scalp, which can slow the delivery of important nutrients to your hair follicles,” explains the pharmacist. “Wearing a hat during cold weather can protect your scalp from the drop in temperature, and gently massaging your scalp can stimulate blood flow and promote healthier hair growth.”

indoor dry heat
Low temperatures are bad for your hair, but central heating can also damage your hair.
“As people stay indoors to escape the cold, the dry heat from central heating systems can strip the scalp and hair of moisture,” warns Phil. “This dryness can cause scalp irritation and lead to hair loss.”
