Exactly 15 mins may be slight more for my hair. 2 shampoos, towel dry and conditioner or treatment/olaplex. Comb through. Then face and body. Double cleanse face and body. Using a loofah or body brush (shock horror!!!) Then that needs rinsing, and so I do, head to toe. Approx 20 mins
If I body exfoliate, that takes a bit longer. Scrub goes on or use body brush leave product on for 5 mins. Same with shaving takes around 5 -10 mins if doing more than just legs and pits.
Sometimes, I will brush my teeth as well in the shower depending on if I have time to kill waiting for a product to work it's magic.
And, sometimes I just zone out. Compling shopping and to do lists.
It's my time to have a little bit of self care daily. Without it, I feel like shit and sluggish.
A pits and bits wash before bed with a quick once over all over is about 10 mins.
I think a lot of ppl underestimate how long they actually spend in the bathroom.
Oh and another few minutes doing toners and face serums afterwards.
