A little farther up the follicle is the mysterious feature called the bulge. That's where follicle stem cells live. When they get the right set of chemical signals, these self-renewing cells divide. They don't divide like normal cells, in which both halves become new cells that keep splitting and developing. Only one half of the follicle stem cell does that. The other half becomes a new stem cell, and stays put for future regeneration.
Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body.[1] Often it results in a few bald spots on the scalp, each about the size of a coin.[2] Psychological stress may result.[2] People are generally otherwise healthy.[2] In a few, all the hair on the scalp or all body hair is lost and loss can be permanent.[1][2]
I live in Orlando. I understand your panic. How old are you? Are you in menopause or peri or is it purely hair loss not horome related? I have been to a dermatologist I traveled 2 hours to another city. I’m like you, desperate and going from doctor to doctor. It’s a nightmare and I’m losing more hair all the time. Where are you losing your hair? on top? Is it diffuse? I feel like I’ve wasted so much time. I felt in November it was menopause related. I went in Menopause early 40s. wasted months on HRT since January and hair worse on top. I felt like I was in a nightmare and nobody understands. You truly don’t want to leave the house. I went to derm specializing in hair loss. He did biopsies. Female pattern hair loss on top. Folicullitis in back. I had even had hair fall out around nape of neck. But he just basically said nothing. I was waiting for biopsy to come back and more blood work and I said can’t I take something. He said you’re not going to lose any in two weeks. I’m like are you kidding me? every week is another nightmare. Anyway he says take spiro 50 mgs, use Rogaine. Even I know from these blogs you need to take 100 to 200 for female hair loss. Basically I go back and he says hair transplant. Did I mention he does hair transplants. So he does nothing beyond diagnosis except offer hair transplant. I’m like My hair is falling out all over. I need to get it stabilized first. sorry I’m rambling. I’m using rogaine foam. It makes me feel good to use it as if I’m doing something. Been on a month almost. Now just went on finasteride, but jury is out if that will help. But even that I asked for from him and his dose was lower than on these sites. So I asked for higher. I wish I could take spiro, but it upsets my stomach horribly. So I’m going to Redmond. I should have gone in January. I can’t believe this is happening to me. I’m sorry I’m rambling.
Today, one of the most common problems that could degrade one's beauty is hair loss. Most individuals usually shed 50 to 100 hairs every day. This loss, usually does not cause noticeable thinning of scalp hair, as new hair simultaneously grows along. Hair loss occurs when this cycle of growth of hair and shedding of hair is disrupted or when the hair follicle is destroyed and replaced with scar tissue. There are a lot of causes of hair loss. Usually hair loss could be heredity or because of family history, can be due to hormonal changes, because of certain medications and also because of some medical conditions or diseases. Several conditions or diseases leads to hair loss. If you are one of those who suffer from loss of hair then you would probably love to read this article which explains about the diseases that cause hair loss.
Ann, I’m so sorry to hear about your home. That breaks my heart for you. I wish you the best in recovery of your home and blessings on your finances. But I do have to say I think that only losing 20 sounds like a dream! I absolutely know that my TE was triggered by PPD in hair dye. I only wish that I would have figured it out sooner. I was forewarned with itching for a year, no dandruff flaking or anything just itching and that was my body trying to heal itself against the allergy and the all hell broke lose on my head! Please keep me posted propecia; I wouldn’t even look for any improvement for 6 months though. But please be here when you do see it! Have a blessed day!
Thank you all for sharing your stories. I have various health issues including arthritis of the spine, GI problem and Poly ovarian cyst syndrom… I had exetremely thick and full hair all my life 5yrs ago my hair started falling out in huge clumps all day long so much so that I leave huge hair balls under my desk at work… I also have sjordren syn. When I first went to my family doctor he told me it was because of my high stress job… I said that I did research on the internet and that all my conditions were supposed to be linked to hairloss he was mad and said why did I come to him if I had all the answers… I have been to 2 dermos who said its nothing. I went to the only endocrinologist in a 100 plus mile radius of my home who was taking new patients who said that there is nothing wrong with me and that if I cared about my health as much as my hair loss I would loss weight ( I know I not skinny but…) he did not even LOOK at my tests when he came in he said we didnt get your urine samples results back. I said that I went 3 weeks ago. He then said oh here they are… but did not even look at them before his fat comment… since I do not want to swear on here I will just say “jerk”. I cried the whole way home. I went back to my family doc and saw the PA because it seems he is sick of me. Again among other sympt. my hairloss is getting worse… the PA’s answer “yea that’s pretty bad.” (wow I’m paying for this advice ) She brought me back samples and said this should help. it was an anti depressant….I said I am not depressed I am upset that everyone can acknowledge my sympt. but no one seems to be able to help my. My arthritis doctor ran tests only to shut me up and said my folate levels were fine so it had to be stress… not their problem. I came from my 3rd gyno today who said now since my cysts were gone and my test. levels were normal that I can’t have children anyhow then I shouldn’t worry about hairloss… no advice whatsoever about the diease less than 5 mins. $400.00 40 mile trip another day of work gone. This doc. did even think I should be concerned that I cannot get preg. or my pain (so it does not surprise me about the hairloss) I said is there anything else that can cause my hair to fall out besides test. levels he said not gyno related…. He said if you like we can test you again in three more months. I would give up but I know it is not something just in my head or even just a cosmetic problem…. I feel sometimes they just want to milk my insurance dry my running the wrong test so they can keep charge you for the expensive stuff instead of working on a cure for you. The worst maybe is that my family and friends are also sick of me and think I just like attention. From your post I looks like a lot of have similar health and experiences. Although I am very upset I am glad be able to vent to people who also my have be treated like hypocons… and armed me will more info.
It is perfectly normal for people to shed 50 to 100 hairs per day. This generally doesn't cause noticeable thinning of scalp hair because new hair is growing in at the same time that hair is shedding. However, hair loss occurs when this hair growth cycle and shedding is disrupted or when the hair follicle becomes destroyed and replaced with scar tissue. Female pattern hair loss (androgenetic alopecia) is the most common form of hair loss in women. This occurs gradually and is caused by genetics (from either side of the family), age, and the action of a specific male hormone, dihydrotestosterone (DHT). This hormone is found in lesser amounts in women and it preys on the hair follicles, preventing them from receiving vital nutrients for proper hair follicle growth, leading to the hairs shrinking, and resulting in a shorter lifespan. Interestingly, DHT does not need to be elevated to generate hair loss. Estrogen, when lowered as commonly seen in menopause, creates a change in the ratio of male to female hormones, giving an edge to these male hormones. Compounded with the sensitivity of DHT to the hair follicles, heredity can affect the age at which a woman begins to lose her hair, as well as the rate of hair loss and the extent of baldness. 
Results from several small studies suggest that biotin supplements may improve thinning hair and brittle nails. Less commonly known as vitamin H, biotin is part of the B complex vitamins, which help your body metabolize fats and protein. Some experts even recommend a daily supplement for everyone since it’s generally safe and pretty hard to get too much of it.
*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®).

Some of the skin disorders like lupus and sarcoidosis can cause hair loss. In case of lupus, the hair tends to get brittle and may fall out in patches. Lupus hairs or short, broken hairs usually appear above the forehead. Hair loss is not permanent in general here. Some individuals with lupus also develop a form of lupus known as discoid or cutaneous lupus that affects the skin. Scars that sometimes develop on the skin of the scalp may lead to hair loss.
The main type of hair loss in women is the same as it is men. It's called androgenetic alopecia, or female (or male) pattern hair loss. In men, hair loss usually begins above the temples, and the receding hairline eventually forms a characteristic "M" shape; hair at the top of the head also thins, often progressing to baldness. In women, androgenetic alopecia begins with gradual thinning at the part line, followed by increasing diffuse hair loss radiating from the top of the head. A woman's hairline rarely recedes, and women rarely become bald. 

I want to say that all of you are very courageous and sharing. I appreciate everything I have read here. Thankfully, I am starting out in a slightly better position – I still have a fair amount of hair left. I started with a HUGE amount of hair. For the last 6 – 12 months, I have been losing handfulls of hair in the shower every morning, then some more when I comb it out, then a bit more when I put styling product in it, then just a bit more during the day. The shower is the huge hit, though. I’m 37 and on a ton of medication – synthroid, neurontin (an amitryptiline derivative), anti-depressants, and a host of pain medications for a degenerative back problem. I brought my hair loss up to a doc around the time it started, since I was already on synthroid, he re-tested my levels, and said everything was fine. My hair structure has always been on the thin side, but there was just so damn much it didn’t matter – now there is a lot less. What used to take upwards of 20 minutes to dry with a dryer, now takes 5. I’ve been worried about it for quite a while, and didn’t know what to do. I started my on-line research today with hair extensions and stumbled on this site. I am encouraged that I’m starting my search for an answer relatively early in my hair loss journey. I have some great advice and questions to go in to see my doc about. If anyone has any recommendations for the Boise, ID area for a dermatologist and endocrinologist, I would really appreciate it.
My hair was healthy. No split ends and thick and tame – I could not break it. The healthy condition of my hair may be the reason that I didn’t loose all of it. My hair loss was due to a “HAIR DESTROYER” causing chemical damage, burning my scalp and my hair ( I think she used a product banned in Australia). I had bald spots on my crown the size of 50 cent pieces and the rest of my hair was singed. I lost my hair gloss, I was left with hair that was as thin a rice paper and breaking everywhere. I had severe itching on my scalp for two years. Not pleasant. I cursed her every day and still do. I bought myself a pair of hairdressing scissors and cut as much hair off as I could; and chipped into it everywhere. I do this every two weeks. Hence I will never go to a hair dresser again and have not colored my hair since December 2012 – I asked for Brown on Brown 10 vol – how could an idiot of a hair destroyer (dresser) get it so wrong.
The pattern of hair loss, especially whether it is focal or diffuse, also may be helpful (Figure 1). The hair-pull test gives a rough estimate of how much hair is being lost.2,4  It is done by grasping a small portion of hair and gently applying traction while sliding the fingers along the hair shafts. Usually one to two hairs are removed with this technique. The hairs are then examined under a microscope (Table 2).
Re-growing hair: It is likely that the hair will grow back even without treatment. It may fall out again, though. Most patients lose their hair more than once before the disease goes away for good. Even people who lose all the hair on their scalp and body can have their hair grow back. When hair loss is widespread (lots of hair loss on the scalp and/or body), there is a greater chance that the hair will not re-grow.
