Anagen effluvium implies abrupt hair loss, mainly impacting the scalp. It most often ensues 7-14 days after chemotherapy exposure. Complete hair loss occurs after 1-2 months.

Anagen effluvium is entirely reversible, with hair regrowth generally emerging after a delay of 3-6 months. Upon the ending of drug therapy, the follicle continues its regular activity within a few weeks.

 

What is anagen effluvium?

Every strand on your body grows from hair under the skin. Hair is nourished by tiny blood vessels that provide oxygenated blood and essential nutrients to promote growth.

The first phase of the hair growth cycle is the anagen or growing phase. This phase can last for several years before the hair moves into the catagen phase for about ten days, then finally transitions to the telogen phase. The final phase is when the follicles rest for two to four months before the old hair falls out to make room for new growth.

Effluvium is used to describe active hair loss of more than 100 hairs per day over two to four weeks. This hair loss is usually classified according to the phase of the growth cycle in which the hair falls out.

Anagen effluvium, then, refers to sudden hair loss affecting the hair in the growing phase. This damage is usually triggered by an event or stress that disrupts the metabolic activity of the hair follicles. One of the most common causes of anagen effluvium is cancer treatment.

 

Is anagen effluvium reversible?

 

Anagen effluvium is also known as chemotherapy-induced alopecia. It is a non-scarring form of alopecia. Anagen effluvium is often reversible.

It results from severe trauma – usually poisoning or inflammation. That disrupts hair follicles' mitotic or metabolic action in the anagen phase. Openness to chemotherapeutic factors such as antimetabolites, alkylating envoys, and mitotic inhibitors are always implicated. Radiotherapy, infections, and autoimmune diseases can also activate this form of hair loss.

Unlike conditions such as telogen effluvium, which pushes hair into the telogen phase, resulting in premature hair loss, anagen effluvium weakens the hair shaft, making it more vulnerable to breakage. In some follicles, it can prevent hair formation.

Damaged hair loss usually occurs within 14 days of the offending stimulus. Fortunately, it is generally reversible – the hair growth process will start again once treatment is stopped.

We talked about How long does anagen effluvium lasts and how it is reversible. Now let's talk about its treatment options.

What are the treatment options for anagen effluvium?

In general, treatment for anagen effluvium aims to limit the amount of time the patient suffers from hair loss.

Because anagen effluvium is usually triggered by chemotherapy or radiation, treatment may not be necessary specifically for hair loss. In many cases, patients experience a full recovery in three to six months to complete their course of treatment.

The only medications sanctioned by research to avoid or decrease the duration of anagen effluvium are scalp cooling therapy and topical minoxidil.

 

Cooling the scalp during chemotherapy

Hair loss is a popular side effect of chemotherapy and radiation medications. Anagen effluvium was the most common adverse effect (78.6 percent) in a total of 1,000 patients undergoing chemotherapy, according to a 2018 study.

Scalp cooling, or hypothermia, has been found to help prevent hair loss in patients undergoing chemotherapy. This therapy helps by prohibiting blood vessels in the scalp to decrease blood flow, restricting the amount of chemo medicine that surpasses the hair follicles. You can utilize an ice pack, cooling cap, or a scalp cooling system.

In one study involving 142 women with breast cancer, more than 50 percent of patients with scalp frizz kept most or all of their hair.

 

Minoxidil

Topical minoxidil comes in 2% and 5% concentrations in liquid and foam forms. Although the exact mechanism through which minoxidil improves hair growth is unknown, research has shown it can trigger hair follicles to enter the growth phase early. In a large 2004 study, more than 84 percent of male participants found minoxidil very practical, effective, or moderately effective in promoting hair growth during 12 months of treatment.

Keep in mind that it may take several months for minoxidil to show its effect. However, several studies have shown that topical minoxidil can reduce the duration of baldness by an average of 50 days.

 

Conclusion

Anagen effluvium is a common side effect of chemotherapy treatment, but the good news is that it is often temporary. Many patients experience regrowth within a few weeks or months after stopping treatment. Some also experience regrowth during treatment.

You are looking for a way to promote hair growth in the meantime, hair loss treatments like minoxidil can help.

If you have hair loss and are not sure How long does anagen effluvium lasts, it is best to talk to your healthcare provider. Your healthcare provider can help determine the root cause of your hair loss and recommend a safe and effective form of treatment.
