Are you familiar with equisetum horse tail plant? It's been around since the dinosaurs!  Loaded with silica, it is a tonic for hair, skin, and nails as well as bone health! I've harvested, dried, and infused argan and coconut oil with the plant material for 4 weeks. Strained the plant material out and added in rosemary, lavender, and cedarwood essential oils; a combination known for promoting  hair growth.
 
I like to massage a dropper full into my scalp and rub into my ends before a sauna or beach outing. My hair is looking healthier than ever! Rosemary is great for brain health so work it into your scalp and leave on as long as you'd like!
