I’m sure your hair absolutely beautiful!
I think it depends on your hairs overall density, curl pattern, etc.
Some days, espeacially if I’ve been stretching for months on end, it takes up to 30-35 mins to just shampoo and wash my hair, let alone try and detangle whenever I did detangle.
My hair at this length now, it’s getting shorter and shorter. One time I timed myself out of curiosity and I was in and out of the shower in less than 10 mins or just about. That included washingnmy body, washing my hair, detangling and rinsing.
On average it takes me 15-20 mins if I’m taking my time somewhat.
When I was natural it took about the same amount of time, but I have insanely fine hair that just softens up and separates under running water. When soaking wet it compresses well over half of it’s normal density when dry, so it behaves under the shower quite a bit.
I have about 33inches of hair, and the biggest thing that takes up time is my scalp. It’s so finicky and sensitive that I typically spend several mins just massaging it and breaking up build up.
I also think some products aid in shower time. Some aid more than others, some more or less for certain hair types. Herbal Essences ensures I’m in and out of the shower lickity split. It’s about the only conditioner that gives me an insanely amount of high moisture and slip. Something thick like TGIN, or SM, or Maui is going to take a min for me to work in and detangle through on account of slippage.
