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.
I have had hair loss for the past several years. I have seen both endocrinologists and dermatologists. I had one derm who was good, but I unfortunately moved. She put me on minoxidil 5% and spironolactone. I am now seeing and endo but he has me on Synthroid and I was very interested to read on this site that it can actually be a cause of hair loss! If anyone can recommend a doctor in Chicago i would appreciate it. I see there are 2 other people asking for recommendations but I haven’t seen responses to them. Thanks!
I am on Arava and my hair has become extremely coarse, frizzy, and tight tight curls in the back. The sides of my hair are pure frizz and the top is straight, with frizz. It used to be smooth and so easy to manage. Now it takes so long and it looks awful. Anyone find the same thing and anything that helps? I have tried so very many hair products, so has my beautician. She says it is like I have 3 completely different textures on my head.
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
Ironically, taking the hormone levothyroxine to treat an underactive thyroid can contribute to some hair loss, among other side effects, but this seems to be more common within the first month of treatment and more often in children than adults. This hair loss is only temporary and will go away as treatment is continued and thyroid hormone levels stabilize.
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.
Some other autoimmune diseases can also lead to hair loss. Lupus, which affects many different systems of the body, is one of them. Symptoms include fatigue, headache, painful joints, anemia, abnormal blood clotting, and hair loss, according to the website LiveStrong. The disease is usually triggered by environmental factors like exposure to the sun. Hashimoto’s disease, which occurs when the immune system attacks the thyroid gland causing an underactive thyroid, can also result in hair loss.
I have been amazed and appreciate alot of peoples’ comments and experiences on hair loss. I recently found out that i have PCOS through an endocrinologist. I went in for an infertility consultation. Still working through that. I do have thinning hair on the top of my head and my hair has become really dry in general. I have type 4b/4c hair (kinky/tightly coiled). With PCOS you have to treat each symptom. I am wondering, if i am focused on infertility right now, am i also able to check in with a dermatologist and treat both? It seems likely that the answer is no. Just curious if anyone is going through this or has gone through this and can give any helpful advice.
Not surprisingly, treatments with 5 percent minoxidil work better than treatments with 2 percent minoxidil. A randomized clinical trial published in the American Journal of Clinical Dermatology in 2002 found that, in men with androgenetic alopecia, “5 percent topical minoxidil was clearly superior to 2 percent topical minoxidil and placebo in increasing hair growth.” The difference was actually pretty astounding — after 48 weeks, the men who used 5 percent minoxidil experienced 45 percent more hair growth than the men who used the 2 percent treatment.
Evaluating and treating hair loss (alopecia) is an important part of primary care, yet many physicians find it complex and confusing. Hair loss affects men and women of all ages and frequently has significant social and psychologic consequences. This article reviews the physiology of normal hair growth, common causes of hair loss, and treatments currently available for alopecia.
I have not heard anyone talk about the “HairClub” use to be a center called the “Hair Club for Men” but now seems to also be catering to women. I had a consultation last week and the consultant looked at my scalp with an instrument that showed my scalp on a screen, she performed a microscopic hair and scalp analysis. Of course I really needed to see my scalp magnified a trillion times and seeing both thick and thin hair and of course all the empty spots where hairs use to be. She was very informative and showed me the cycle of healthy hair and also the ones that are not and how they thin and eventually fall out and the hair follicle closing. Their pamphlet show women with different stages of hair lost, from patches to almost bald. She explained that there was hope and that with a yearlong regiment of going once a month and having my scalp treated with their products and some sort of scalp stimulation I can get my hair back. Of course this comes at a price, almost 3k for the year. She did say that the monthly regiment will include hair styling as well. woohooo. Anyways I want to know if anyone has been to one of these Hair club facilities and if they have had any success with the personalized program without having to resort to surgery. My prayers go out to all of you.
