Triamcinolone acetonide (Kenalog), 0.1 mL diluted in sterile saline to 10 mg per mL, is injected intradermally at multiple sites within the area to a maximum dosage of 2 mL per visit.6 The main side effect, atrophy, can be minimized by not injecting too superficially and by limiting the volume per site and the frequency of injection (no more often than every four to six weeks).6 Because spontaneous resolution often occurs in patients with alopecia areata, assessing treatment response can be difficult. Intralesional steroids should be discontinued after six months if no improvement has been noted.
Family history will often tell the doctor what type of alopecia a person has. Occasionally, a punch biopsy may be necessary to determine the type of hair loss. Looking at plucked hairs under a microscope can help to tell the difference between alopecia areata and androgenic alopecia. Other tests might be done to check for autoimmune diseases like lupus that can accompany alopecia.
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.
Trying to figure out exactly what is causing your hair loss is going to require a little detective work on the part of your physician. Several lab tests are going to need to be done. I’ll make sure to make another post this week about the standard lab tests that should be ordered to start the process. Hopefully you don’t have to bring the list to the doctors office, he/she should know already. I get concerned when women have to bring a list of tests that should be ordered to their doctor. My feeling is that if they don’t know what to order then how are they going to be able to accurately read the results. But… a good doctor is a good doctor, and if you have one that really cares and takes a strong interest in your hair loss with a willingness to work with you in finding the cause then great.
Speaking of a new style: Don’t choose one that’s so high maintenance that it needs to be heat styled daily—the damage you’ll do with too much hot tool usage can leave strands damaged and fried, and breaking before it can grow to a certain length. Plus, thinner hair tends to break easier, so you want to avoid any extra damage-inducing practices at all costs. Make a conscious effort, too, to brush more gently, and use a moisturizing and reparative hair mask to hydrate hair and nourish the scalp—where hair gets most of its strength.
Diffuse female hair thinning and hair loss during premenopausal age is usually not heredity. It is usually caused by hormonal imbalances seeing in PCOS or thyroid disorder, nutritional deficiency (low iron), and stress. Women with PCOS produce high levels of androgens such as testosterones and DHEAS. The ratio of LH and FSH is also more than 2. Make sure you get your sex hormones check if you notice your hair thinning.
