25 yo, 7 years of hair loss - Advice needed

[Hair87]

I have been reading through these forums since very long time, now decided to join.
Hair (Here) is my story:-
1. Baldness runs through my family. (My father is NW 5V)
2. Started losing hair at 18 (Triggered early due to extreme stress and poor health)
3. At 21, concerned with continued hair loss, went to a clinic specializing in hair loss treatments.
Medication i am taking since then:-

• Saw palmetto capsule (Powder 100mg+Extract 250mg) - Twice a day first year, once a day afterwards
• Hair oil with Saw Palmetto (every alternate night)
• Shampoo with Saw Palmetto (next day of applying oil)
• Multivitamin with 10mg biotin (Once a day)
• R89 Homeopathic medicine
• Laser therapy - on and off (like one session a month)

Result:-Was able to maintain my hair for 4 years, lived a healthy and stress free life.
Side Effects:-Almost Nil

Situation Now:-
Got a job six months ago. Stress returned and so did my hair fall.
Diffuse thinning all over. Scalp is very much visible. New hair that are coming are very thin and week. Hairline has receded around half an inch or so. Major thinning has happened around the crown area.

Advice needed:-
I still think i can do some more to help maintain my existing hair.

Options i have:

• Finasteride
• Minoxidil
• PRP
• Nizoral Shampoo
• LL Laser Therapy (Have tried this before but was not regular)

What options would you suggest? What changes shall i make to my current regime?
