"Is it permissible not to shave or shorten the hair after Umrah for someone who shaved their hair before it? "

Shaving or trimming the hair is one of the rituals of Hajj and Umrah, either as an obligation or an essential act. Those who have hair on their heads must shave or trim it, while those who are bald are recommended to pass a razor over their heads. Shaving is preferable to trimming, especially if the hair is very short. For those intending to perform two consecutive Umrahs, it is better to trim the hair during the first Umrah to allow for shaving in the second one, provided there is not enough time for hair growth between them. Similarly, this applies to those performing Tamattu' (combining Umrah and Hajj).
