hloo sir, my baby is 6 month old and her hair growth is still slow. till end of 4 month her almost hairs have fallen. and after 4 month new hairs are growing but still there is less growth of hair. she is still not achieved the growth of her birth time hair. at the time of birth she has very smooth and full of hairs. after birth she was in nicu for 15 days because of some difficulties in breathing. does it affects her hair growth?
