Using cold water in hair washing can help seal the hair cuticle, leading to shinier and smoother hair. The hair cuticle is the outermost layer of the hair shaft, and when it is sealed, it lies flat against the hair strand. This flat, closed position reflects light better, which contributes to a shinier appearance. Cold water also helps to reduce frizz and enhance the overall texture of the hair by minimizing moisture loss, leading to smoother and healthier-looking locks.

In contrast to this, options pertaining to promoting dandruff or making hair more frizzy do not align with the effects of cold water. Cold water does not inherently cause dandruff since dandruff is primarily associated with scalp conditions and not the temperature of the water used. Similarly, while frizz can be caused by several factors, using cold water tends to prevent hair from becoming frizzy, especially when compared to hot water, which can strip moisture and lead to frizz. The assertion that cold water slows down hair growth is also inaccurate, as hair growth is influenced by other factors such as genetics and nutrition, and not significantly affected by washing temperature.
