hmm.... how can you classify mastery with all the different hair types we have. lol IMO a natural 2a/2b//3a/3b does not have as difficult a time as a natural 4b/4zzz in taking care of their hair. 3b hair natural = 4b texlaxed in some cases. In that case, mastery should be based on hair type as well shouldn't it?
this statement is really on point.. i totally agree.
