I use Aubrey Organics and can testify that they are great -
You want to look out for
preservatives like parabens, dmdm hydantoin, glydant, phenoxyethanol, polyquaternium, surfactants like
SLS and betaine, colors and fragrances. (all natural surfactants, colors and fragrances may be okay)
Basically any chemical derived materials have higher probability of being harmful.
Stick to all natural if possible.
