Detailed answer

Yes, allergies to certain skincare products have the potential to cause thinning hair. When an individual is allergic to a specific ingredient in a skincare product, their body's immune system reacts by releasing histamines, which can cause inflammation and irritation in the scalp. This inflammation can disrupt the hair follicles and lead to hair thinning or hair loss. It is important to identify the allergen causing the allergic reaction and avoid using products that contain it. Consulting with a dermatologist or allergist is recommended to determine the specific allergen and establish a suitable skincare routine to prevent further hair loss.
