The bulb means is shedding rather than breakage, this thread
is a bit of a read but there is alot of info. There's a little test to help you figure out how to react to your hair. There are varying degrees of how heavy a protein is so bare that in mind when you do pick a protein treatment. I tend to mix amla to the consistency of mashed potato and leave it to sit awhile before I apply it. when I apply it I only apply it to the strands. Amla and henna have helped me with shedding but everyone is different.
Garlic tablets might help if you don't fancy paying those charges? I had a quick google try this thread
and this thread
also for what others have tried. I know you said you don't want to rub/dc with it but it seems to help.
Hopefully someone else will help too!
oh p.s I got my amla etc from spices of india in case you're in need
