My elder son have sensitive skin and always scratches his legs until bleed.. so I cannot use those off-the-shelves bath wash.
Tried a few organic brands, and I feel nature's gate and sudzy (amway) are good enough for him. Now, His skin heal a lot, and no more scratching. Nature's gate is natural, unscented and comes in a huge bottle (value for money). Bought around 12plus from Qoo10. I learn about Sudzy brand from my friend. Their bath gel and herbal shampoo each comes in a small bottle (275ml).
Though small packaging but only $9-$10 a bottle. And my boys smell good after shower.
