Does Hair Loss Reduce After Shaving Head?

No - shaving does not affect hair loss. It will change the appearance of the scalp, and may alter the appearance of hair density, as the length of the hair and how it is styled can greatly affect the appearance of hair density. Genetics, hormones, and medical conditions can play a role in hair loss, but shaving does not. If hair loss is significant, hair transplantation may be an option.
All the best,

This is an urban legend, old wives tale, a misconception.For men, the most common cause of hair loss is genetic male pattern balding. Shaving has nothing to do with hair loss reduction (other than you probably won't see the long hairs that are falling out since you shaved).

Shaving your head may disguise hair loss, but it will not have any affect on the condition itself. Whether hair is thinning due to pattern baldness, or some other cause, it is usually either a hormonal or nutritional reaction at the root of the problem. The origin of the condition must be addressed in order to reduce hair loss.

No, shaving your head will not affect the rate of hair loss.  Hair loss is most strongly determined by genetics.  Keeping the hair shaved may reduce the noticeability of shedding as the hairs are shorter, but otherwise will not contribute.

Unfortunately, shaving your head will not decrease hair loss. For the most part, hair loss is caused by genetics, or medication, or a number of other issues. However, some short hair cuts can help to hide hair loss where it sits. There's lots of information online for suggested haircuts to help hide minor hairless. 

Actual loss of hair follicles is not reduced by shaving ones head. Hair in the follicle if it was in an active shedding phase, may come out within shaving.

Shaving the head has no effect whatsoever on hair growth. It does not accelerate hair growth, reduce hair loss or promote any changes.

Short answer....No. Most hair loss is caused by androgenetic alopecia or male/female pattern hair loss. This is caused by hormones and your hair follicles' response to a particular hormone (DHT). Thus, shaving your head does not impact your hair loss although for a lot of men the current trend to shave or close cropped hair helps to hide their hair loss (think Bruce Willis or Jason Statham).

The two items that may improve hair loss are Rogaine and Propecia. Both work well for androgenetic alopecia (Propecia not for female pattern hair loss). Both work in about 2/3 of the men that use the products. Both work best in early stages of hair loss, and both only work while you are taking the product. Even for men undergoing hair restoration surgery, in my opinion one or both products may be helpful because it helps to hold onto the hair that you already have and may grow additional hair (i.e. an addition to the hair being transplanted). Both of these possibilities help to improve the final cosmetic appearance following hair restoration surgery. Rogaine is available over the counter, and Propecia is a prescription medications. Best option is to talk to a board-certified dermatologist to be sure of the cause of your hairloss and discuss what are the best options for you. Good luck.

Shaving does not reduce hair loss. Although it may give the impression that you are losing hair, because you may not notice as much hair falling when the hair is real short. 

It is an old wives tale that if you shave your head, the new hair will return and become thicker. This is not true
