Hi - Essential oils specifically noted for sunblock include Sea Buckthorn and Sandlwood. Personally, I use several of the CO2 oils as a skin protectant - mostly for their strong antioxidant activity. Again, Sea Buckthorn, Carrot Root, Rosehip CO2, Frankincense and Sandalwood. Small amounts of Rosemary CO2 (it doesn't smell too strongly!) can be added as well, as it has very special and potent antioxidant activities.

It was Sea Buckthorn that was studied by Russian Cosmonauts as a potential blocking agent from intense rays encountered in outer space

For hair loss, a base of Tamanu, Virgin Coconut and Rosehip Seed, with Helichrysum (5%), German Chamomile (1%), Rosemary Verbenone (3%), and Carrot Root (1%) may be an excellent choice. Anti-inflammatory and stimulating.
