Merry Christmas @SophieF.
WEN can work for everyone because it is completely customizable to your particular hair type (which you didn't mention), and hair needs, which is changeable.
Ultimately, its just wash, rinse, and repeat, like any other hair wash.
Beyond wash-rinse-repeat, how much time, money, and effort you want to put into your hair is up to you.
If you're wise enough to stick with WEN, in time you'll have to change your hair routine because your hair will improve, and not need the same as what needs today.
Start with these videos from Chaz's website just to get a general idea.

You can go a long way toward improving your hair with just cleansing conditioner. It's very versitile. Forget the ancillary products for now.
As you'll see in the vids:
Thoroughly saturate hair w water
Cleanse scalp and hair using 2 to 3* golf ball sized blobs of WEN, and adding more water after the WEN is on scalp and hair.
*Use more WEN if your hair is closely waved or curly/kinky/coily
As you see in the vids, add more water to help spread WEN from scalp to ends. This should work up into a frothy consistency.
This isnt a co-cleanse. If it stays real creamy you need lots more water.
Rinse well
Repeat the cleanse as above, and rinse scalp & hair thoroughly.
As you'll see in vids, add a leave-in amount of cleansing conditioner to sopping wet hair, starting at the ends and working upwards. Avoid applying leave-in to scalp.
common mistakes on both wash and rinse:
Not enough WEN
Not enough water
being skimpy with both WEN and water
skipping the Repeat cleanse
or continuing to use (ugh!) shampoo
After hair improves a bit you might consider trimming your frayed broken ends for a better finished look.
But this is enough to get you started. 🎄
