How long after head lice get onto my head would they start laying the eggs/nits?

It depends on where: they are in their life cycle when they get onto your head. There are adult males and females and only the females lay eggs.

I got slapped hard on the head by my brother. Can a hard slap change the shape of my head and how much until my little pain on the head goes away?

I got slapped hard on the head by my brother. Can a hard slap change the shape of my head and how much until my little pain on the head goes away?

No change of bone: At your age the bones are well fixed and solid. A hard enough slap from a very strong, agressive person might fracture the bone, but not change its shape. The pain is almost certainly from the bruising that the slap gave you. Hopefully he will not do this again. ...Read more

Here are some ...: Without a direct look at it, it's hard to offer a reliable Dx. So, bring the onset, degree, duration, & progress of the little bump over time to Doc or urologist for analysis + inspection + tests such as biopsy as needed only. Clinically, it may be just an inborn harmless lesion such as mole or HPV. Therefore, seek pro-evaluation timely. ...Read more

How to treat flaking on the head of a 2 month old baby?

Tea tree Shampoo: Up until 2-4 months we call that flaking cradle cap or cradle crap as one of my moms said. You can use mineral oil or baby oil...Etc..I found that tea tree shampoo used daly (do not get in the eyes) worked well after two months. There is some evidence that it may be fungal based and hence tea tree oil shampoo works well. Tea tree oil alone is too strong for tender scalp. ...Read more

Touch top of head tender and get dizzy from concussion a month ago not knocked out how long to heal and skull has bump on it, I've been fine?

Touch top of head  tender and get dizzy from concussion a month ago not knocked out how long to heal and skull has bump on it, I've been fine?

Variable: With your symptoms I'd say the range for everything to clear would be on the order of several weeks to several months. Head blows which then, cause significant effects of headaches, dizziness, difficulty concentrating, "goose eggs" on the scalp etc. usually heal by then. Sometimes they can take longer but the good news is things WILL heal given time AND no further similar insults while healing. ...Read more

Hair on top of my head was plucked during haircut, leaving bald/thin spot. How long and what should I do to take care of my hair for it to grow back?

It will grow back: all by itself. Hair which is pulled out by the root will eventually grow back. In fact, there are many invisible hair follicles immediately adjacent to the pulled out hair which may start growing even before the pulled hair grows back. You should return to normal in a few weeks without doing anything special. Find another barber, tho' ! ...Read more

How long does it take for flat spots of head to go away, 
my daughter is 11months has flat spot on left and back of head, which is noticeable. ?

Depends: By the time baby is spending more of her time upright & not laying down, gravity is no longer aggravating the process as much & it has a chance to round out. If the skull is visibly distorted, shifting one ear& part of the face forward as seen from above, a specialized helmet can be worn to help speed the reshaping. Most become un-noticeable with time & as hair thickens. ...Read more
