I started losing my hair after my plastic surgery. I had a brow lift and facelift, is there anyways to reverse this?

It can be common for some hair loss after a surgical procedure like a facelift. This should resolve over the next several weeks. If it persists, I recommend following up with a hair loss expert. I hope this helps. 

Some hair loss is seen every now and then with the brow lift and facelift.  It is usually temporary and due to either stress on the hair follicle or an actual injury to the hair follicle from the scalpel during the incision or when using electrocautery close to the skin.
In cases where the hair follicles have been permanently injured, which is rare, there are options.  Neograft hair transplant is the treatment of choice for our practice to provide hair to areas of hair loss or alopecia.
I want to encourage you to be patient b/c hairs will go through cycles that consist of growth, rest, and death.  They then repeat this cycle so you must be patient for weeks to months to see if the hairs will return to the growth phase
