Long term ACV -hair loss

After 6 months of taking 5-7tablespoon ACV (organic with mother) a day internally
Iam experiencing hair loss (Im male, 21yrs, good nutrition, lots of physical activity etc.)

Im pretty sure it is caused by the ACV because my mother and my brother who used it with me are experiencing the same symptoms

So what does ACV deplete in long term or how can i reverse the caused damage?
Could the alkalinity be the cause?
