I Got a Hair Cut And I Noticed a Bald Spot.

I got a hair cut in May and all my hair was growing except one spot
not its july and it’s getting bigger.

I would see a doctor about this. It may be alopecia areata from just the photo alone. If it is alopecia areata your hair will grow back over time without any treatment. But it may also return and it even can progress. See a doctor and get a definitive diagnosis.
