When the hair is totally drenched in the water molecules or in any part of liquid substances, it basically shows its springy type of puffiness nature which resembles like curly type of appearance. When compared to the straight hairs, in intense equatorial climatic conditions may enhance the more comfort levels in these climatic, structural conditions which tend alternatively to naturally fall of hairs on ears and neck to a degree that provides to the comfort levels in various cold climates relatively too tightly coiled type of hairs. Whereas some other researcher interrupts or interpret the ideas of some most famous researchers in suggesting the various trait techniques which resembles the hair texture considered to be too trivial for natural selection have been played a vital role in this phenomenon. And they also added the argument that the researcher explanation is only about the sexual selection and it is mainly responsible for such kind of traits.

Hence on the other hand, when talking about the sexual selection hypothesis cannot be ruled out totally.
