Is this a normal amount of shedding?

Is this a normal amount of shedding after having an cornrow crochet hairstyle for six weeks. First photo after I took out my braids. Second photo after I detangled conditioned hair. Last photo of the comparison of the two. I recently started taking hair supplements to help with my hair growth. But wondering if this is a normal amount of shedding or what can I do to prevent shedding while having protective styles in for six weeks?
