Diffuse Thinning, Hair Transplant Surgery, and Other Top Solutions: What You Need to Know

August 9, 2022

Diffuse thinning, hair transplant surgery is not usually the first treatment that is recommended for this condition. While it is a very common cause of hair loss, diffuse thinning is different from pattern balding. Instead of only affecting a concentrated area such as the hair surrounding the face, or the crown of the head, diffuse thinning can cause hair loss throughout the scalp. This can cause the hair to thin, and to have an almost see-through appearance in the more advanced stages. 

In this article, we will discuss diffuse thinning, hair transplant surgery, and other less invasive methods of treatment. We will also discuss the different causes of diffuse thinning, ways to prevent it, and how to know whether hair transplant surgery is your best option in the long term. We’ll discuss what to do if you suspect that you are dealing with diffuse thinning and which ineffective treatments to avoid. 

Diffuse thinning can affect both men and women. It describes a loss of hair density overall, instead of the classic horseshoe pattern that is often observed in male pattern baldness. A person experiencing diffuse thinning may notice accelerated shedding of the hair, greater space between the individual strands of hair on the scalp, or a tinner braid or ponytail when styling their hair. This can obviously be very disheartening, but in most instances, this condition is both temporary and treatable. 

One of the most obvious signs that you are experiencing diffuse thinning is excessive shedding. You may notice more hair is falling out in the shower, or you may find more hair in your combo or brush. You may even find more hair stuck to the shoulders of a jacket or sweater. Before you panic though, keep in mind that it is normal to shed hair on a daily basis. On average our scalp sheds about 100 strands of hair per day. By comparison, the average human head contains anywhere from 80,000 to 120,000 hair follicles. 

Hair goes through a natural cycle of growing, resting, and shedding that lasts between 2-6 years. During the Anagen, or growth phase, the hair is actively growing longer. This phase lasts between 2-6 years and 80-90 percent of one’s hair is in this stage at any given time. The Telogen or resting phase is when the hair is no longer actively growing but has not been shed yet. 10-15% of one’s hair will be in this phase at any given time. This stage usually lasts between two to three months. Less than 5% of one’s hair is in the Catagen or transitional phase in which it is shed, at any given time. This transitional phase generally lasts around 6 weeks. Once you understand the cycle of growth for a strand of hair, it is easier to understand why shedding a small amount of hair on a regular basis is completely natural and normal. Some people literally collect and count the hairs they shed in the shower or while styling as a way to check to see whether the amount they are shedding is within a healthy range. 

When it comes to diffuse thinning, there are many different causes. One of the biggest culprits is known as “telogen effluvium” which is basically a fancy word for excessive shedding. A person is experiencing telogen effluvium when a large number of hairs prematurely enter the telogen, or resting phase of the hair cycle leading them to fall out sooner than they normally would. Instead of 80-90% of the hair is in the growing or anagen stage, as much as 70 percent of the hairs that should be growing end this phase prematurely, and wind up being shed. 

Telogen Effluvium is one of the ways that the body reacts to physiologic stresses, which can be caused my several factors. These include serious illness, for example many people who had covid 19 report an increase in hair shedding after their illness. High fevers are another cause of telogen effluvium. In addition to this, infections, and major surgeries can disrupt the hair growth cycle.  Furthermore drastic changes in hormone levels such as during the post partum phase after giving birth can cause increased hair loss. During pregnancy the anagen or growth stage is prolonged but about 3 months after giving birth, most women notice an increase amount of shedding. This usually resolves on its own. Traumatic life events, or prolonged periods of psychological stress can contribute to diffuse thinning as well. Other causes include thyroid imbalances, crash diets or disordered eating, nutritional deficiencies, and side effects to certain medications can all cause the body to experience telogen effluvium, leading to diffuse thinning hair. Sometimes over exposure to heavy metals such as arsenic, mercury, thallium, lead or cadmium can contribute to telogen effluvium as well. 

More often than not, diffuse thinning as a result of telogen effluvium resolves on its own. After about 3-6 months the hair’s normal hair growth cycle returns to a more balanced state. If this thinning and excessive shedding has not resolved after six months then there may be a sign that you are experiencing chronic telogen efflucium, which is a little more serious. This condition is prevalent among middle aged women in particular and the cause of this condition is unclear. Research suggest that it may be a confluence of factors including stress, hormonal changes, thyroid imbalances, and nutritional deficiencies etc. When it comes to nutritional deficiencies, low protein intake or iron deficiency are the most common issues. Medications especially beta-blockers, retinoids, and anticoagulants have side effects that can contribute to diffuse thinning as well. 

If you suspect that you as suffering from diffuse thinning we recommend visiting a doctor that specializes in hair loss or a dermatologist, you may want to visit your regular doctor as well.  They may be able to order tests to help determine whether hormone imbalances, low iron, or heavy metal exposure are contributing to your present condition. They can help you determine whether any medication you may be taking is causing this diffuse thinning as a side effect as well. For example, certain birth control pills can trigger increased shedding. Knowledge is power, and this information will help you determine the healthiest and most effective treatment for you in the long term. 

Its worth noting as well that female pattern hair loss can also cause diffuse thinning. This is a type of pattern hair loss that causes hair loss around the hair that frames that face and at the part line. If left untreated, it can eventually affect the hair across the entire scalp. You doctor will be able to test to determine whether the cause of one’s thinning hair is related to pattern hair loss or telogen effluvium. Doctors are able to determine if its telogen effluvium by doing a hair pull test and biopsy. A complete blood count, thyrotropin tests, and other quick blood tests can also be helpful in determining whether common causes of telogen effluvium are at work.  

Because the causes of diffuse thinning are diverse, the treatment plans will also vary depending on the individual. Many times a patient will employ several strategies including medication, lifestyle changes, and products that address hair loss. This is why testing to determine the root cause is so important, it will help you determine the best treatments to employ to restore balance. Sometimes its simple things like adjusting your diet to include more protein and iron. Relaxation techniques such as getting regular massages, practicing meditation, or getting reiki treatments can help reduce stress. If hair thinning is occurring after a major illness or surgery, something as simple as increased rest can help. 

Minoxidil, a topical hair medication that is commercially known as Rogaine is often suggested as a non invasive treatment for diffuse thinning. It is available as either a spray liquid or foam and is applied directly to the scalp. It works by encouraging hairs to shift into the anagen or growth phase by stimulating blood flow to the scalp. This can help to promote the appearance of thicker, denser hair. 

Finasteride is a prescription medication intended to treat hair loss from elevated testosterone or dihydrotestosterone (DHT) levels. DHT is thought to be the hormone responsible for male pattern baldness. DHT impacts accelerated hair loss by shrinking hair follicles in the scalp. Finesteride is very effective for hair loss that’s caused by DHT but it has not been shown to help with diffuse thinning due to telogen effluvium. 

Shampoos that claim to promote hair growth are rarely effective for treating diffuse thinning. If hair thinning is occurring due to some kind of infection or imbalance in the scalp, there are shampoos that a dermatologist may prescribe to correct this, but there is little proof that hair growth shampoos are very effective. Same goes for hair growth vitamins, particularly those that boast biotin as their active ingredient, there is not any evidence that products such as these will do much to improve the growth of your hair. 

When it comes to the question of diffuse thinning, hair transplant surgery and whether or not it is an appropriate treatment is also complicated. Not everyone that is experiencing diffuse thinning is a good candidate for a hair transplant. If the patient lacks the hair density required to obtain enough follicular grafts to transplant into the balding areas, the transplant will wind up looking unnatural and the patient will be unhappy. If the hair follicles at the donor site are being impacted by DHT this can also exclude them from being a good candidate for hair transplant surgeries because the donor follicles will be at risk for shrinking over time. 

So you’re experiencing diffuse thinning, hair transplant surgery is not a good fit for you, so what do you do instead? Well, another treatment option to consider is Low Level Laser Therapy (LLLT). LLLT was first approved by the FDA in 2007 for the purpose of treating mild to moderate hair loss. LLLT has been shown to increase cell metabolism, and improve the health of blood vessels in the scalp. This helps the hair follicles to produce hair shafts that are thicker and more more durable. It also stimulates the sebaceous glands, giving the hair a smoother and shinier appearance. On top of that it boosts melanin production, which can darken the pigment in grey hair. Whether used independently or in conjunction with other treatments such as hair transplant surgery, LLLT has been shown to improve outcomes in patients experiencing hair loss. 

Not all LLLT devices are of the same quality. The only devices that are worth spending your money on are laser caps that are prescribed by a doctor that contain prescription grade laser diodes. There are are many products that contain weak laser diodes or LED lights that are ineffective. At Best Hair Transplant we are proud to offer our patients the Capillus82, Capillus202, CapillusPro (formerly the Capillus272 Pro) and the Capillus272 OfficePro. All of these devices have received a 510(k) clearance from the FDA. This is an important premarket notification made to the FDA to demonstrate that this device is safe and effective, based on clinical studies that demonstrate its efficacy. 

A 510(k) is a premarket notification made to FDA to demonstrate that a device is safe and effective. For a medical device to be legally marketed in the United States, it must receive clearance by the Food & Drug Administration. Clearance is based on an application by the manufacturer of the device to the FDA. This application may include clinical studies that prove efficacy, as well as safety information, and other evidence showing that the device is has been deemed safe and effective for its intended use. It is important to be aware of this distinction as there are many devices in the market that have not been granted this clearance and therefore are potentially risky for use.
