oh for sure....and some have extra ingredients to have the hair stronger and thicker...so at least breakage will be minimised.
do make sure you brush your hair...the scalp needs the stimulation. Not overdo, but at least once or twice a day.
Many psychologically know that touching hair pulls it out, so they don't brush it or even want to wash it...just makes it seem like more falls out when they finally do wash it.
Remember, normally, we lose 50 - 100 hair a day...and the whole head is replaced every 2 - 6 years depending on how long each follicle produces a hair before replacing it.
You've had illness which exacerbate any of the above as well as certain meds...so hang tough...it'll be a bumpy ride until your hair growth cycle levels out.
There are also products that will smooth too much and make the hair feel flat and fine, others can spread the cuticle and make it feel "rougher" and fuller....so, if you've found what makes your hair feel and look good...you will feel better.....that's really the point.
Oh, just wanted to add (if you do so) to not put your hair up in those huge jaw clips...they can cause breakage at the scalp...so, how you style your hair and put it up (if you do so) can be a factor.
We don't say we're having a bad hair day or a good hair day without any truth to it. I can relate!
