What shampoo and conditioner do your teenage boys use?

[Topbird29]

Just reviewing my DS13 and DS11 shower routines. They currently tend to use 2 in 1 shampoo/shower gel, but now thinking they may need to use a separate shampoo (maybe conditioner too but not sure if needed). Both have pretty normal hair - not greasy due to hormones yet and neither use styling products. Looking for recommendations that aren't too spendy, ideally drugstore or supermarket and don't smell of strong fragrances. Otherwise, we might revert to Johnsons baby shampoo (but decant it to save embarrassment!)

DS1 (21) uses anti-dandruff shampoo as he needs to.

DS2 (18) usually uses tressame (or however you spell it) shampoo and conditioner. He does have almost waist length, slightly curly hair though.

Before too long you’ll be glad if they even shower! DC went through the phase of just being smelly and grimy about 14 and having to be reminded/persuaded/bribed to shower so whatever is quickest and works is best. I think he had head and shoulders 2 in 1.
Having passed that phase, and with a GF, he now has fancier shampoo, conditioner and styling products than I do. Buys them himself though.
Go for speed and if they want to continue what they have that’s fine. Plenty of men use shower gel/shampoo in one.

Head and shoulders which keeps his dandruff at bay. Hair powder (not fussed about brand) for styling.

DS1 - vosene shampoo. No conditioner.
DS2 - Alberto balsam tee tree oil shampoo. Also no conditioner

Edit: just seen the not too smelly bit. Neither is probably suitable - although DS2 is funny about smells and this passes. Strongly scented, but not girly!

Thanks all. DH bought some Head & Shoulders 2 in 1 for them to try out.
