can any one help? i want to treat my husband who has dandruff, we have come up with Rosemary as an oil, tested for reactions all ok. someone suggested that i add it to a base shampoo which sounded good. But he also has dry hair from the use of all that gel he cakes on leach morn lol, has anyone got any ideas of some oils i can add to a base conditioner to help nourish his hair, or any other suggestions on how i can soften it after he has used the rosemary oil for his dandruff? Thanks XX
