In the blog I posted last week Atlas Cedarwood was listed as being effective for hair loss. Here is some research to back up that claim.
Randomized Trial of Aromatherapy – Successful Treatment for Alopecia Areata.

To investigate the efficacy of aromatherapy in the treatment of patients with alopecia areata.
A randomized, double-blind, controlled trial of 7 months’ duration, with follow-up at 3 and 7 months.
Dermatology outpatient department.
Eighty-six patients diagnosed as having alopecia areata.
Eighty-six patients were randomized into 2 groups. The active group massaged essential oils (thyme, rosemary, lavender, and cedarwood) in a mixture of carrier oils (jojoba and grapeseed) into their scalp daily. The control group used only carrier oils for their massage, also daily. The oils were massaged into the scalp for a minimum of 2 minutes and a warm towel was wrapped around the head to aid absorption of the oils. They were advised to used this technique every night. The active group received the essential oil blend: Thyme vulgaris (2 drops, 88 mg), Lavandula angustifolia (3 drops, 108 mg), Rosmarinus officinalis (3 drops, 114 ml) and Cedrus atlantica (2 drops, 94 mg) diluted in a carrier consisting of 3 ml jojoba and 20 ml grapeseed oil. The control group used just the carrier oils.
Main Outcome Measures
Treatment success was evaluated on sequential photographs by 2 dermatologists (I.C.H. and A.D.O.) independently. Similarly, the degree of improvement was measured by 2 methods: a 6-point scale and computerized analysis of traced areas of alopecia.
Nineteen (44%) of 43 patients in the active group showed improvement compared with 6 (15%) of 41 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 (κ=0.84). The degree of improvement on photographic assessment was significant (P=.05). Demographic analysis showed that the 2 groups were well matched for prognostic factors.
The results show aromatherapy to be a safe and effective treatment for alopecia areata. Treatment with these essential oils was significantly more effective than treatment with the carrier oil alone (P=.008 for the primary outcome measure). We also successfully applied an evidence-based method to an alternative therapy.
Certainly worth a try if you are considering making up a blend for hair loss.
Here are a couple of other studies I found but both studies were conducted on animals.
Inhalation of Cedrus atlantica essential oil alleviates pain behavior through activation of descending pain modulation pathways in a mouse model of postoperative pain

Cedrus atlantica essential oil (CaEO) presents analgesic and anti-inflammatory sedative properties. However, it remains unknown whether CaEO alleviates acute postoperative pain.
Materials and methods
Here, we investigated the effect of CaEO on postoperative pain and its mechanisms related to the descending pain control in Swiss males mice induced by a plantar incision surgery (PIS) in the hindpaw.
Inhalation of CaEO (5′, 30′ or 60′) markedly reduced mechanical hypersensitivity. This effect was prevented by pre-treatment with naloxone or p-chlorophenylalanine methyl ester (PCPA, 100 mg/kg, i.p.)-induced depletion of serotonin. In addition, p-alpha-methyl-para-tyrosin (AMPT, 100 mg/kg, i.p.)-induced depletion of norepinephrine, intraperitoneal injection of the α2-adrenergic receptor antagonist yohimbine (0.15 mg/kg, i.p.) or haloperidol (1 mg/kg, i.p.) an antagonist of dopaminergic (D1 and D2) receptors prevented the effect of CaEO on hypersensitivity.
These findings suggest that CaEO alleviates postoperative pain by activating the descending pain modulation pathways on the opioidergic, serotonergic, noradrenergic (α2-adrenergic) and dopaminergic (dopamine D1 and D2 receptors) systems.
Gastric antisecretory and antiulcer activities of Cedrus deodara (Roxb.) Loud. in Wistar rats
Avadhesh Kumar, Vandana Singh, Amrendra Kumar Chaudhary
Ethnopharmacological relevance: Cedrus deodara (Roxb.) Loud. is used in Ayurvedic medicine to treat peptic ulcer.
Aim of the study
To evaluate the gastric antisecretory and antiulcer activity of Cedrus deodara.
Materials and methods
The volatile oil extracted by steam distillation of Cedrus deodara wood was examined for its gastric antisecretory and antiulcer effect in the pylorus-ligated rat model and ethanol induced gastric lesions in rats.
The volatile oil showed significant antisecretory activity as evidenced by decreased gastric fluid volume, total acidity, free acidity and increase in the pH of the gastric fluid in pylorus-ligated rats. Our studies also revealed that pre-treatment with Cedrus deodara significantly reduced the number of ulcer, ulcer score and ulcer index in pylorus-ligated and ethanol treated rats. The antiulcer activity of Cedrus deodara is further supported by histopathological study which showed protection of mucosal layer from ulceration and inflammation.
The present findings conclude that volatile oil of Cedrus deodara wood has potent antisecretory and antiulcer effects and justify the traditional usage of this herb to treat peptic ulcers.
Volatile oil of Cedrus deodara (100 mg/kg body weight) showed significant reduction in number of ulcers, ulcer score and ulcer index in experimental ulcer induced by ethanol.
