Haircare after swimming

[Realitygf]

I swim up to 3 times a week in a chlorinated pool. My hair is highlighted, thin and I am menopausal so it is quite dry and brittle.
Although I wear a swimming hat, my hair is in a right old state. Any tips/products for sorting it out and making me look less of a state, please?
My hairdresser says just stop swimming!

Leave in conditioner. Briogeo makes a lovely non fragranced with oat and aloe.

Ultraswim shampoo. Or any other shampoo with a decent amount of sodium thiosulphate.

Chlorine bonds to the hair and normal shampoos don't remove it. The sodium thiosulphate reacts with the chlorine to form sodium chloride, which you can then rinse away.

Is swim 5x and have brown balayaged caramal hair. I was worried about my hair before i started swimming but it is fine. I have thin fine peri hair.

Saturate hair with with clean water before putting in swim cap.

I got some soft stretchy thick bobbles from primark that are easy to get out of wet hair - I think the elastics also damage wet hair. Put in a low bun and snap on cap.

Wash at pool as soon as finished session
Blow dry at home using a gentle method - I use a revlon one step.
Use colour WOW dream coat one a week
Other times use hair oil and blow dry spray. Currently using keratin oil from Pantene despite trying loads it the best. Put it on at pool to allow to soak in. Blow dry spray is the Schwarzkopf volume one from Home Bargains - again cheap but works!

Current shampoo is hask volume and it smell gorgeous but also use Aldi fake olaplex.

Ultra swim sounds good.

Most pools have less chlorine in now and use UV "filtration" so you could ask pool how heavily chlorinated it is.

I don't like it when people suggest putting on product before getting in the pool as it does wash out into the pool water. Which we then swim in. Swimming so much (plenty of time to ruminated on such things) I am acutely away of what I am swimming in how ultra dilute it is but please don't add to the concoction of fluids!
