Try d.e.

My hair started falling out, and I found a protocol that really works to bring it back. First, hair falls out for many reasons, but stress and nutrient deficiency are the most common. This is what I did:
First, I started putting castor oil on my scalp -- just the scalp. It's thick so you can dilute it 50/50 with another oil. I used coconut oil, but olive oil will do, and it's cheaper. I put mine on at night and slept with a shower cap on to keep it off the pillow. You can just put it on for 2 hours, then wash it out. If you have mites in your scalp, this will kill those suckers. In fact, some people say this is why it helps your hair grow back.
What I use now is easier, although I still put castor oil on my edges when I need to.
I mix 1 tablespoon of diatomaceous earth in a glass of water and drink that every night on an empty stomach. DE is 85% silica, and it grows hair and nails like mad, plus it will help your skin. Be careful not to breathe it in, but it won't kill you if you do. You may cough a little. I always drink it down, then drink another glass of plain water to wash it out of my mouth.
Supplements: Biotin, CLA, Dopa Mucuna (also kills parasites), B-Complex (stress destroys B-vitamins, so this is good to take anyway) and Vit. E (don't take too much of this, EFA (essential fatty acids - I take one with fish oil, borage oil and flaxseed oil).

The DE is the bomb! My hair grew back fast, thick and darker. I had gone almost completely grey, but most of the new hair is coming in brown.

Hope this helps.

ETA: Also want to say that you need to work up to the 1 tablespoon of DE. I started at 1/2 tsp. and worked up over a number of weeks. It also kills parasites, so you may get some detox symptoms out of it.

I found a herb to regrow hair.

Hi,

Hair fall could be because of several reasons. The main reasons for hair fall are tension, stress, diet, medication and harsh chemicals used on the hair.

I just thought of something...the only thing I've been doing differently the past year is I started smoking weed....and also very routinely.

Hi,

The main reason for hair fall is stress, tension and improper diet. Today hair fall problems are more because of the lifestyle we lead today. No proper sleep, unhealthy eating habits, stress etc.. If we control these we can for sure prevent hair fall.

Hi,

First you need to find out why your hair is falling because there are several reasons for hair fall or it is better you consult a dermatologist to get his / her opinion.

Hi,

There could be several reasons why your hair is falling out. First you need to find out the reason. It could be because of stress, tension, high medication due to some illness etc..

Lost all my hair on three separate occasions. Doctor diagnosed B-12 deficiency and anemia. Started B-12 sublingual - Methylcobalamin (the kind of B-12 which doesn't need to be digested through your stomach - absorbed under your tongue) with B-6, folic acid and Biotin. My ferritin (stored iron) levels were plenty high enough to sustain hair growth.

Amazing how that little vitamin B-12 changed 8 separate blood factors that were bad on my CBC blood panel and my hair has grown back just as thick. It did take about 6 months to stop feeling so tried. Without the B-12, you won't have the iron in your blood cells that you need for everything else.

Now, I also found out I have disseminated dwarf tapeworms. The disseminated dwarf tapes sucker onto the ends of my eyelashes and loves my eyebrows. I keep losing areas of my eyebrows. Bought a microscope and couldn't believe my eyes - dwarf tapeworms. I'm now on MattK3's protocol and am much better, but still in the middle of it so, time will tell. I have found OccuSoft Plus lid wipes are so good. Use them in the morning and evening - I cut one pad into 4 pieces so they last longer. If you have a jeweler hoop and look at the pads after you use them on your eye lid and eyebrow, you can see the parasites. They get caught on the pad.

It could be thyroid, but because of hair loss, I would also ask the doctor for a CBC, to check ferritin, TIBC, and Iron levels.
