I am curious about reviews of hair loss treatments.

As I entered my late 20s, I noticed my hairline gradually widening, so lately I feel so self-conscious that I can't go out without using Hair Pang Pang or wearing a hat. It is so stressful seeing myself constantly worried that my bangs will split whenever the wind blows. I have started taking medication, but I heard that it is difficult to fill in the already thinning hairline with medication alone, so I am considering combining it with professional hair loss treatments.

Has anyone received hair loss treatments, such as scalp injections or lasers, to stimulate fine hair growth along the hairline? I am curious if these treatments can be effective as a step before resorting to a hair transplant. I would be extremely grateful for realistic reviews on whether the pain is tolerable and if it interferes with daily activities (like going to work or washing my hair).
