I’m not trying to suggest that swimming causes MPB or anything like that. I’m just wondering if the chlorine or other chemicals in the pool could be detrimental for those of us already struggling?
The chlorine in the swimming pool may damage your hair, but the growth mechanism is below the scalp, not reached by the pool water. There is a difference between damage to hair that has already grown and new hair that just emerges into your world. If you look at a long hair carefully, the part of the hair closes to the scalp is new and in its best shape, unless your have miniaturization associated with genetic hair loss
