Today, the ancient Libyan race still survives in remote parts of the Rif in Morocco and among the Kabyles of Algeria. Their descendants are still to be found in the mountainous parts of the coast, those of Algeria being commonly known under the name of Kabyles.
And they plot with East African populations becasue they did share an ancestral group that expanded from southern Egypt or Nubia about 24k ago- not because an east African population moved into Egypt.
Evidence for Variable Selective Pressures at MC1R
To sum up then, all the evidence I have indicates that the nature of hair does not alter after death except in becoming dry and brittle. As a researcher, you should not promote your findings based on what you like or not. Their descendants are still to be found in the mountainous parts of the coast, those of Algeria being commonly known under the name of Kabyles. Especially the ones who like to dress up in strange garb looking like refugees from a Cecil B. Equally telling is the little known fact that the active MC1R gene responsible for red hair actually originates in and is widely visible though out Africa. You also might want to look up the age of the L3 and M mutations as you seem a bit unfamiliar with them.
