Hair loss is unpredictable, cause it could be linked to genetic, lack of vitamins, and change in the metabolism or external environment. All that you have to do is to start taking precautions by using vitamins and hair care products rich in Biotin. Also, PRP injection helps with hair restoration and regrowth. and maybe in a later plan, you can get a hair transplant to get your new hairline and more density up the front

You can get a Hair transplant to re-drow your hairline and give it density in the front. The process is really easy and permanent, maximum of 3 days, and 5 days to recover. The results will be shown from 6 to 12 months and
There is the unshaved hair transplant where you won't have to shave all your hair. Only the donor area will be shaved to extract grafts and it can be covered by your hair, later on, to grow back normally.
For the technique, I advise you to get DHI direct hair implantation with a Choi pen. it gives 100% results, a natural look where the surgeon can control the direction of the graft to give it the natural shape especially the front line.

It depends on the technique, With DHI it won't be much of a problem, after 3 days you can go back to eating solid food. if you want to be extra careful you can wait until the 7th day as an extra caution.
With DHI Choi pen, the grafts will be placed directly into the specific places without creating channels to receive. its like injecting the graft into your mustache and beard patches. there won't be any scars and of course less bleeding.
the only thing that you should be careful about is water, rubbing the grafts, and sleeping mood. Also you should follow the doctor's aftercare advice to eliminate any mistakes

PRP injections are a good treatment to enhance the metabolism of the grafts and nutrition. It about extracting the rich plasma in your blood and re-inject it into your scalp to refresh your hair. It's advisable to get PRP injection even after HT to help growing your hair
My only concern is doing Second FUE. You already used the Sapphire blade before to create channels for the reception. Now it's not advisable to do 2nd FUE because it may damage your existing grafts and finally you can lose them. There is DHI technique with a Choi pen, It's perfect for adding density and filling up the gaps between your hair follicles to give it a more natural look. With Choi pen the surgeon can implant up to 200 grafts per 1 cm2 to give you the density you are looking for.
All I can say choose wisely so you won't regret it later

Depending on your donor area, you can get a hair transplant with DHI technique. It will give you the density you are looking for and a natural look due to the fact that the surgeon will have the ability to control the graft direction while implanting it. It's a permanent solution and the results will be shown after 12 months.
