Could I be allergic/sensitive to bleach or chlorine? Reactions have progressed to hives, facial swelling, and throat swelling

I smoke marijuana nightly. I haven't had any alcohol in over 4 years and don't use any other recreational drugs.

Like the title says, I'm wondering if I have some type of allergy or severe sensitivity to bleach/chlorine. I'm not sure if the two things I'm experiencing are actually related, but the reactions to both seem to have gotten progressively worse over the years.

I started dying my hair vibrant colors about 10 to 12 years ago. As a natural brunette, I had to constantly bleach my hair light light blonde to get the vivid colors to stick. When I first started bleaching my hair, my scalp would burn while the bleach was processing, but once it was rinsed out, I was fine. I noticed that the burning became worse each time I had my hair done. Eventually it became very painful.

Around four years after starting the vivids, the reactions became much more severe. Bleaching my roots became increasingly painful, and eventually I developed what appeared to be chemical burns/sores on my scalp that required antibiotics and an ointment.

The second and third to last times I used bleach on my scalp, my face became extremely swollen (nearly twice its normal size) and bright red.

The final time I bleached my roots, I accidentally inhaled some of the powder/fumes when my hairstylist poured the bleach into the mixing bowl. Shortly afterward, my throat started to swell and I had to take benadryl.

Then there's chlorine.

For the past 4 or 5 years, I haven't been able to swim in a chlorinated pool without developing extremely itchy hives. If I'm in the water for more than a couple of minutes, the hives spread over most of my body.

I've also stopped going to water parks because the strong chlorine smell seems to trigger my epilepsy. I've had a seizure at a water park on two separate occasions, so I decided it wasn't worth the risk.

More recently, over the past 3ish years, I've started developing itchy hives from showering as well. My showers are becoming shorter and shorter because the hives seem to appear faster and are becoming more severe. If I shower for longer than about five minutes, I have to take at least two Benadryl afterward because of the itching/hives.

I'm not sure whether all of these reactions are connected or if there could be something else going on, especially since I'm now reacting to shower water.

Is this something I should bring up with my primary care doctor, or would it make more sense to see an allergist or dermatologist? Are there particular conditions or allergies I should ask about?

I really miss being able to take a long shower and go swimming with my family, and I'm concerned that the reactions seem to be getting progressively worse.

I'm attaching a link to imgur to show pictures of the hives. I got the hives in the pictures just from showering. I didn't think to take pictures until 20 to 30 minutes after I popped two benadryl. One of the pics is somewhat not safe for work. The pictures are of my upper chest, chest, stomach, and arm.
