Aromatherapy
In 1998 double-blind study published in the Archives of Dermatology found that 44 percent of participants who massaged their scalps with a mixture of essential oils daily for seven months showed growth in bald patches. The tonic was composed of active essential oils including:

2 drops thyme vulgaris (88-mg)
3 drops lavandula agustifolia (108-mg)
3 drops rosmarinus officinalis (114-mg)
2 drops cedrus atlantica (94-mg)

and used the carrier oils:

jojoba oil 3-ml
grapeseed oil 20-ml (NOT grapefruit seed oil)
In the study 86 volunteers with alopecia areata massaged oils into the scalp each evening for a minimum of 2 minutes; followed with warm towel wrap to aid absorption of oils for about an hour. Half of them received the complete tonic and half of them received the carrier oils alone as a control.
The results were that 19 (44%) of 43 patients in the active group showed improvement compared with 6 (15%) of patients in the control group (P = .008). An alopecia scale was applied by blinded observers on sequential photographs and was shown to be reproducible with good interobserver agreement.
The investigators concluded that the results showed aromatherapy to be a safe and effective treatment for alopecia areata. Treatment with the essential oils was significantly more effective than treatment with the carrier oil alone. (Hay IC, Jamieson M, Ormerod AD. Randomized trial of aromatherapy.

5 ml = 1/6 oz

15 ml = ½ oz

30 ml – 1 oz

1 ml = 20 drops
