Rinsing hair in tepid or warm water is the most appropriate option because using cold or hot water may cause damage to the hair. Cold water could cause shock to the hair strands, making them more prone to breakage. Hot water, on the other hand, can strip off essential oils and moisture from the hair, resulting in dryness and potential damage. Using icy water is also not recommended as it can be too extreme for the scalp and could cause discomfort. Therefore, rinsing with tepid or warm water is the best way to remove lightener without causing harm to the hair.
