Hello and welcome to HealthcareMagic
You seem to have what is called post partum hair loss. This usually starts in the third or fourth month postpartum and ends by six months. This is a temporary phase.
During
pregnancy the increased levels of estrogens in your body makes your hair thick and lusturous, hair that would normally fall out stays put, resulting in thicker hair. After delivery when estrogen levels fall you start losing all those hair that were resting during pregnancy.
This temporary hair loss doesn't mean you're deficient in nutrition or vitamins, infact its hormonal.
I would advice to take a good healthy diet, continue with your Iron and
calcium supplements and Vit D supplements till you are breast feeding. Take a high protein diet because hair is all protein(keratin).
Morr lotion is claimed to curb
hair fall and stimulate hair regrowth. It should not be used by pregnant and nursing mothers.
Regarding the scalp bumps, there seems to be a bacterial infection of the hair follicles/
folliculitis. If i was your treating doctor i would have put you on
oral antibiotics (penicillin group, safe in pregnancy and nursing mothers)for a week, which should make it fine
take care
regards
