Deep conditioners are specialized hair care products designed to provide intense moisture and nourishment to the hair. They typically contain rich ingredients like oils, proteins, and botanicals that penetrate the hair shaft, helping to repair damage and improve overall texture. Deep conditioning treatments are often used once a week or as needed, depending on the hair's condition. These products are particularly beneficial for those with curly, coily, or damaged hair, as they help to restore elasticity and reduce frizz. Applying a deep conditioner usually involves leaving it on the hair for a longer period, allowing the ingredients to work effectively for healthier, shinier locks.
