Thanks for posting your query.
I will be glad to be of assistance.
Any chemical treatment however safer can result in textural changes in the hair, can cause a lot of hair fall
Even if you do any preventive treatment the changes may take place.
you could apply minoxidil
while having the treatment, but it may not really stop the changes.
You could do the keratin treatment and apply minoxidil only later on if required in case of any baldness
Please use a conditioner after every hair wash.
Hope my recommendations are helpful.
Please let me know if I can address any additional concerns for you.
