I have noticed something about some fictional alien races. For example, Male Skrulls do not have hair on their scalp although some have facial hair. On the other hand, female Skrulls have hair on their heads. In Captain Marvel film, both male and female Skrulls are bald.
Male Durlans, Chamelon Boy's people in DC comics, are bald, too but female Durlans have hair on their scalp.
Male Zenn-Lans, Silver Surfer's people, have bald heads although some of them have facial hair. Female Zenn-Lans such as Shalla Bal have hair on their scalp.
Both male and female Ferengi are hairless.
Male Bolians have bald heads, as do some female Bolians. But other Bolian women have hair on their heads.
Does it make sense that the men of a race have bald heads while the women of the same race have hair?
