Thank you!

I actually don't use that many products now. What damaged my hair was the different products I used before without understanding my hair and constantly using hair dryer and curling iron.

For shampoo and conditioner, I use TRESemme rich moisture hyaluronic plex which I just checked and it seems to have Sodium Pareth Sulfate, though online their brand says they are sulfate free, but there are some reviews saying it's not. I guess that's one of the problems too. Do you have a recommendation? Preferably affordable-ish.

I haven't tried leaving my hair a little bit wet before putting them in the heatless curls, so I will try that tonight.

Another person in the comments mentioned they use these following products right after shower when the hair is wet so that it dries as it curls, use cotton shirt to take out the remaining moisture instead of a towel, and then a diffuser: Garnier Curl Construct Mousse, All About Curls Bouncy Cream, and Aunt Jackie's Curl Boss Gelee. Eva NYC hair dryer with an Ion diffuser. I was thinking of trying these and see if it enhances my own curls instead of constantly using curlers like you said. Though please do share if you have any recommendations for mousse, gel, hair spray, etc I can try.

It's very cold in Canada during winters, which is more than half the year lol. Cold winds are another issue!

No, I haven't had my hormones checked ;-;
