Hair fall 5 months after hair transplant (~2500 hairs on the hairline) FUE

Hi! I am 18 years old and i have androgenic alopecia. Its been 6 months that i had my transplant and the results are good. I had no hair loss after the procedure until 5 months but after that i had intense hairloss around 40-60 hairs everyday (both the native and the transplanted) the transplanted hairs have become thin and the density also reduced. I already had 4 sessions in 4 months of low light therpy with prp, but as the sessions were over hairsfall began.
