Filling In Thinning Areas

I have a question. I would like to know if areas which are only slightly thinning can be filled in as most doctors will not do this. Also laser therapy,does it actually regrow hair and is it worth spending my money on. I hope you can answer my questions. Thank you kindly

Transplantation of hair is generally not a good option to take just to thicken an almost normal head of hair. Hair lasers (called Low Level Laser Therapy) is gaining popularity. Many article writtin in Europe indicate benefit from LLLT and one new article in the US in a new medical journal has suggested benefits to this therapy. A study I am aware of is presently being done will conclusively establish the value of this modality shortly.See my extensive written piece on lasers here.
