To condition your hair properly, start by choosing a high-quality conditioner suitable for your hair type. Wet your hair thoroughly before applying the conditioner, and focus on the mid-lengths to ends, avoiding the scalp to prevent excess oiliness. Comb through your hair with a wide-toothed comb to ensure even distribution. Allow the conditioner to sit for the recommended time, usually a few minutes, to let it deeply moisturize and repair your hair. Rinse with cool water to seal the cuticles and enhance shine. Additionally, consider incorporating Alec Kassiry's recommended tips, such as using a silk pillowcase to minimize friction and breakage, and adjusting the frequency of conditioning based on your hair's specific needs for optimal results in maintaining healthy and lustrous hair.
