who lost his strength when his hair was cut
Samson The biblical account states that Samson was a Nazirite, and that he was given immense strength to aid him against his enemies and allow him to perform glorious feats,[2] such as killing a lion with his bare hands, slaying an entire army with only the jawbone of an ass, and destroying a temple of the Philistines with his bare hands. However, if Samson's long hair was cut, then his Nazirite vow would be violated, and he would lose his strength.[3]
Human hair color Children born with some hair colors may find it gradually darkens as they grow. Many blond, light brown, or red haired infants experience this. This is caused by genes being turned off and on during early childhood and puberty.[17]
