A shrinking ponytail, a part that keeps getting wider. What can be more upsetting than realizing our hair is falling out? After all, a dense, healthy mane is a sign of beauty and vitality for many of us. 

Thinning impacts more than one out of two women by age 70, according to the Mayo Clinic. Female pattern hair loss (FPHL), identified by progressive shedding, is the most common cause. 

Though there are many different ways to treat FPHL, incorporating a serum into your routine is an excellent place to start. The best serums for hair regrowth combine ingredients that not only slow thinning but nourish your scalp and hydrate your strands for longer, thicker locks. 

How Your Hair Grows 

Each of your strands grows from a follicle — a tiny tunnel-shaped organ that extends into your skin’s deeper dermal layers. At the base of the follicle is a root where shaft construction occurs, fed by a network of microscopic blood vessels that deliver essential nutrients. 

New layers are continually added at the bottom of the shaft, composed of a protein called keratin. As new keratin layers form in the root, older layers are pushed through your skin’s surface, giving your hair its length. 

Eventually, your strand stops growing, and your follicle releases the hair. At this point, your follicle enters a resting phase before restarting the process. 

How Your Hair Stops Growing 

During menopause, estrogen and progesterone levels drop, and your scalp is left vulnerable to dihydrotestosterone (DHT). Scientists approximate that the 5-alpha-reductase (5α-R) enzyme changes 5-10% of your body's testosterone into DHT. 

Your liver, skin, follicles, and other tissues metabolize the male hormone. Next, it travels through your circulatory system, where it flows to androgen receptors on different tissues in your body. 

DHT attaches to your follicle’s many androgen receptors causing your follicles to shrink. Follicle shrinkage leads to finer, brittle hair that breaks and sheds easily. 

Elevated DHT lengthens your hair’s resting phase (telogen) and shortens the growing (anagen) phase. An abbreviated growth cycle means hair falls out before reaching its max length. 

A Guide to Hair Growth Serum Ingredients 

Hair thinning does not have to be your new normal. Many topical scalp serums are effective at stimulating growth and regrowth. The following are ingredients found in serums proven effective at treating FPHL: 


Minoxidil is a medication that has become a household name synonymous with hair regrowth. Originally developed as a treatment method for stomach ulcers and high blood pressure, it had a unique side effect that caught the researchers' attention — excess hair growth

Now primarily marketed as a hair growth treatment, minoxidil dilates blood vessels and stimulates follicles back into their growth phase. Why is this important? With more active follicles, your overall volume and thickness increases. 

Topical Finasteride 

Finasteride is a 5α-R inhibitor approved for men and off-label use for post-menopausal women. Some studies involving women failed to prove finasteride in pill form had any notable effect on hair loss prevention. It was also attributed to congenital disabilities in the babies of pre-menopausal women.  

In 2020, 119 post-menopausal patients took part in a study where researchers evaluated topical finasteride as a possible hair loss treatment. Finasteride applied topically had fewer side effects than the pill form. The researchers reported a "valid therapeutic option" in treating post-menopausal FPHL. 

The participants showed the most significant improvement following 12 to 18 months of receiving topical finasteride. 


Of course, we are all familiar with the energizing effects of caffeine in our morning coffee. But did you know that caffeine can be just as invigorating to your follicles? 

Similar to minoxidil, serums with caffeine increase scalp circulation when applied topically. They also include the following benefits: 

  • Increased ATP — Adenosine triphosphate (ATP) is a molecular compound that provides energy to follicular cells and delays their transition to dormancy. Caffeine elevates your cells’ ATP metabolization and amplifies its effects.
  • Inhibiting DHT — When left unchecked, DHT impedes essential proteins, vitamins, and minerals from reaching your scalp’s capillaries. Caffeine has been shown to neutralize DHT’s hair-thinning effects. 

Oleanolic Acid 

Oleanolic acid is a phytochemical found in basil, java apples, olive oil, garlic, honey mesquite, clove, and more. It is used to treat various health issues, including androgenetic alopecia. 

Oleanolic acid is added to scalp serums to curb thinning and increase thickness. It is often utilized as a natural alternative to synthetic DHT and 5α-R inhibitors. Additionally, research evidence has shown oleanolic acid can spur the reproduction of fast-growing hair matrix cells resulting in: 

  • A new anagen-like growth stage.
  • Longer shaft lengths. 


Estrogen is a hormone group mainly produced in the ovaries that extends your hair’s growth phase when present. When estrogen levels drop during menopause, your follicles into the resting phase due to a gene called the Transforming Growth Factor Beta 1 (TGFbeta1). 

Apigenin is a chemical compound present in many plants, including chamomile and parsley. Researchers have shown that apigenin inhibits TFGbeta1 effects and delays your follicles from entering the catagen phase. 

Simply put, TFGbeta1 sends a signal to your strands to stop growing. Serums with apigenin reduce the effect of TFGbeta1, keeping your hairs rooted in place.
