So far from the ones i have tried (from dm drug store), kii-baa natural baby shampoo was most suitable for me, (GTIN: 8593085000970). Before i have used alverde family shampoo (4066447523683) which had an ok smell but was quite drying (and contains coco-sulfate), but i didn't know a better one at the time. The ones from balea were pretty bad (parfumed, left coating on hair), and the solid shampoos either from alverde or nature box just left my hair dry and very difficult to untangle, despite using also solid conditioner, so do not recommend.
