Detailed answer

Yes, allergies to skincare products have the potential to cause ridges on nails. When a person is allergic to specific ingredients in skincare products, their body may release histamines as a response. Histamines can affect the blood vessels and the nail matrix, leading to a disruption in nail growth and the formation of ridges. Additionally, some ingredients in skincare products can cause dryness or inflammation around the nail bed, which can also contribute to the development of ridges on the nails. It is important to identify and avoid the allergen or irritant causing the reaction to prevent further nail damage and seek medical advice or consult with a dermatologist for proper diagnosis and treatment.
