never heard of dax wax but I have long wavy hair which is frizzy I can't brush it when dry only when wet, so I wash my hair everyday, brush it and I put just a small amount and hair wax in my hands rub my hands together then transfer through the hair focussing on the ends esp and not the top scalp section. This keeps the locks from going frizzy, and makes the locks set in place for the day.
Just been to look what I use and its 'wella shock waves re-create styling wax' I have used it for 10 years at least and it last for ages. I bought a cheap hair wax once for £1 and it smelt horrible and had a terrible texture. This applies nicely. I bought the wrong one recently by mistake not wanting to open the lid in the shop, but you have to to make sure, you want the thick hard wax, not gel, not clay, it's solid and you have to almost scratch the surface at times to get some out
