I can't see the pics! But that is probably because I am at work and they are blocked
But I think that there is potential damage from BS if you a leaving it in your hair for long periods of time. Any alkaline substance will lift the cuticle and the more alkaline the more dangerous. But because hair is acidic, almost everything we use is more alkaline then our hair.
This is why some ladies swear by ACV rinses and recommend them after BS clarifying to restore the hair's natural ph balance.
I wouls suggest everything in moderation and closely monitoring the situation to find out what works for your hair.
For me, I am hoping that BS will be a much safer replacement for my relaxer so I am willing to give it a go an take it further than a lot of others might.
