Effective Hair Washing Tips
Temperature matters - lukewarm water opens hair cuticles and helps remove dirt without stripping natural oils. Hot water dries out your scalp and hair.
Apply shampoo to your hands first, not directly to your head. Work it into a lather before applying to your scalp with fingertips - not your nails, which can scratch your scalp. Massage thoroughly to clean every part of your scalp.
For particularly dirty hair, lather, rinse, and repeat for a thorough clean.
