Order Rosemary & Cedarwood essential oils. Plant Therapy & Eden’s Garden are good companies. Add the oils to your shampoo. I can’t find an article to support the correct amount. I believe it’s ten drops per four oz shampoo. I used a small bottle instead of putting it all in my large bottle. I altered the oils each month. I haven’t had Covid but I had such bad hair loss it felt like spiders were crawling on my arms. It started a few months after the plandemic started. I read a article there was a big increase in dermatology patients seeking hair loss remedies. It’s was an even mix of people that had Covid & didn’t. Sounds like just the stress of everything was also causing it. I dealt with hair loss a decade ago when I lost weight. Any upset in the bodies balance will trigger hair loss, especially with women. Hair loss is different than breakage. Many men experience hair breakage & it leads to baldness.

I like Rosemary & Cedarwood for myself because I like the scents. Look up foods that help with hair loss. You can also try selenium foods. There’s also a selenium supplement.

Using a plant based shampoo is better for our hair and body. However I don’t believe shampoo has much affect on hair loss or fixing it. We have to repair what’s going on inside. There’s many reasons we loose hair. I have read people that had Covid might have hair loss. When I was using the essential oil in shampoo I was also taking full spectrum CBD regularly. In addition I was eating healthier. I stopped the CBD & my eating habits became worse over the winter. I’m now starting to notice hair loss again. I’m female, 55 & on estrogen & still loosing hair. I have once again started CBD. Good luck, I know how frustrating it can be. If you don’t use the plant based shampoo and need suggestions I can recommend ones I have used.
