It’s totally natural and often expected to lose hair as you age. However, it still takes a toll on your confidence as you see your once-thick hair fade away. Understand how hair grows and what your scalp needs to wake your follicles back up and start growing your hair again!

Hair Growth Cycle

The hair growth cycle is a complex process regulated by a variety of hormones and factors. This cycle is unique to everyone. Age, genetics, hormones, stress, and various medical conditions affect it. The three stages of the hair growth cycle are:

  1. Anagen (growth phase): This is the longest phase of the hair growth cycle, lasting anywhere from two to eight years. During this phase, the hair follicle is actively producing new hair, and the hair shaft grows at a rate of about one centimeter per month.

  2. Catagen (transition phase): This phase is relatively short, lasting for about two weeks. During this phase, the hair follicle shrinks, and the hair shaft stops growing.

  3. Telogen (resting phase): During this phase, which lasts about three months, the hair shaft sheds, and a new hair follicle starts to grow in its place. The cycle then returns to the anagen phase, where a new hair is grown.

The percentage of hair follicles in each phase of the hair growth cycle varies depending on the location of the hair. For example, the hair follicles on the scalp are mostly in the anagen phase, while the hair follicles on the eyebrows are mostly in the telogen phase.

When someone loses hair, it’s usually because the hair follicles are entering the telogen phase prematurely. This is often due to age, hormones, and other factors that affect hair growth. As you age, your anagen phase gets shorter, causing you to lose hair and causing hair loss.

According to the Mayo Clinic, “See your doctor if you are distressed by persistent hair loss in you or your child and want to pursue treatment. For women who are experiencing a receding hairline (frontal fibrosing alopecia), talk with your doctor about early treatment to avoid significant permanent baldness. Also talk to your doctor if you notice sudden or patchy hair loss or more than usual hair loss when combing or washing your or your child’s hair. Sudden hair loss can signal an underlying medical condition that requires treatment.”

Hair Regrowth

There are countless reasons to lose hair: male or female pattern baldness, genetics, age, scalp conditions, stress, and more. While it’s difficult to fight your body’s natural chain of events and regrow hair, it’s possible to increase hair growth and extend your anagen phase. It’s best to regrow your hair during early signs of balding, such as excessive hair loss, slow growth, decreased hair density, and bald spots.

Hair regrowth is a complex process that involves the activation of dormant hair follicles and the growth of new hair. The hair follicle reenters the anagen phase, where new cells gather to create the hair shaft. The hair shaft pushes out the old hair shaft and grows out of the scalp. The hair follicle remains in the anagen phase for a period of time, which varies depending on the individual and the location of the hair. The hair then continues through the catagen and telogen phase.

The goal of hair regrowth is to extend the length of time that your hair is in the anagen phase. This gives your scalp a chance to grow hair in a follicle that was previously dormant — stuck in the telogen phase after shedding.

The amount of time it takes for hair to regrow after thinning or balding depends on the underlying cause of the hair loss and the effectiveness of the treatment. If the hair loss is due to a temporary condition, such as stress or illness, the hair usually grows back once the underlying condition heals. If the hair loss is due to a permanent condition, such as male pattern baldness, hair regrowth may be possible with medical treatment or surgery.

Regrowing Your Hair

There are a few ways to start to regrow your hair. The best way for you depends on the cause of your hair loss and your individual circumstances. Start by nourishing your body and scalp by eating a healthy diet rich in vitamins and minerals, getting adequate sleep, managing stress, avoiding heat styling, avoiding harsh chemicals on your scalp and hair, and massaging your scalp regularly with your fingertips or a scalp massager.

These home remedies should be a part of your daily routine to promote hair growth and care for your scalp. Although, these methods alone won’t regrow your hair. Here are some of the most common hair regrowth treatments:

  • Minoxidil (Rogaine): Minoxidil is a topical medication that stimulates hair growth. It’s available over-the-counter and as a prescription medication.

  • Finasteride (Propecia): Finasteride is an oral medication that blocks the production of DHT, a hormone that causes hair loss. It’s only available by prescription.

  • Hair transplantation: Hair transplantation is a surgical procedure that transplants hair follicles from one area of the scalp to another area.

  • Platelet-rich plasma therapy (PRP): PRP is the process of drawing blood from your arm, separating the platelets from your blood, and injecting them into your scalp to stimulate hair growth.

  • Laser therapy: Laser therapy uses low-level lasers to stimulate hair growth. It’s not as effective as other treatments, but it’s a great option for people who don’t want to take medication or have surgery.

  • Topical treatments: Topical treatments containing ingredients such as minoxidil, finasteride, saw palmetto, caffeine, biotin, and other vitamins and minerals stimulate hair growth. Apply these serums to your scalp regularly to promote growth.

Hair Serums for Hair Regrowth

There are hair serums for increased volume, added shine, frizz control, heat protection, and hair regrowth. Hair serums for hair regrowth are topical products that contain active ingredients such as minoxidil, finasteride, saw palmetto, caffeine, biotin, and other vitamins and minerals.

Hair serums stimulate hair growth by increasing blood flow to the scalp, providing nutrients to the hair follicles, reducing inflammation on the scalp, and blocking the production of DHT (a hormone that causes hair loss). The effectiveness of hair serums for hair regrowth varies from person to person. Some people see results within a few months, while others may not see any results. Be patient and consistent with the use of hair serums for the best chances of growing long locks again.

Hair serums aren’t a cure for hair loss. They can stimulate hair growth but cannot cure baldness. If you’re concerned about hair loss, see a doctor or dermatologist to determine the cause of your hair loss and discuss the best treatment options.
