My handmade herbal shampoo with Rosemary and Lavender is a lovely mild shampoo that can be used regularly on all types of hair. Rosemary and Lavender are the best essential oils for conditioning the hair and Rosemary is reputed to be able to stimulate hair growth. Wash the hair once with the herbal shampoo, massaging the rich lather into the scalp. Rinse with clean water then apply Nettle Hair Conditioner.
