Best serum for hair growth and thickness

Styling hair in an iron-tight bun during a workout will keep it out of your face, but it can also put pressure on fragile strands, leading to breakages and, worst-case scenario, a sparse hairline.

If you think you might be looking a bit sparse up top, you're not alone. According to a recent study by Philip Kingsley, 75% of women admitted to being concerned about hair loss or thinning. Whether it be due to stress or hormones, hair thinning is not a concern that’s exclusive to men.

A good hair growth serum can help rectify the problem. They're formulated to promote growth and prevent breakages, to leave you with fuller and longer-looking hair. But while they're hard-working, these serums aren't miracle workers, so don’t expect to see a complete hair transformation overnight. And, as always, check in with your GP if your hair loss is becoming a greater concern.

Keep scrolling to find out the best hair growth serums that impressed our panel of 285 testers...

What causes hair loss?

We asked Consultant Dermatologist and Hair Specialist, Dr Sharon Wong, to explain why hair loss may occur. Dr Wong says:

'Intermittent shedding can be due to underlying genetic hair loss, periods of time when sex hormones are in flux; e.g. stopping/changing/ starting contraceptive, hormone replacement therapy, dietary changes, stress or after pregnancy. Seasonal shedding can also play a part, as some people are sensitive to the number of daylight hours'.

Our diet (as always) is also an important factor:

'Healthy hair growth also requires good nutritional support from the inside. Our follicles are highly metabolic mini-organs and use up a lot of energy. A well-balanced diet that includes the full spectrum of macro and micronutrients is the best and most sustainable way of supporting healthy hair growth (and a healthy body in general),' says Dr Wong.

How we test

The Women’s Health Lab asked 285 people to try 19 hair growth serums for 8 weeks, to see if they really gave them longer, thicker hair.

Testers looked for any improvements in hair density, strengthening and regrowth, as well as monitoring any changes to their scalps.

The WH team also used a Hair Metrix machine in the lab to measure hair follicle regrowth with each serum.

What Causes Hair Loss Or Thinning Hair?

Many facts can cause hair loss. However, you should always find the root causes so you can find the best hair growth product to restore your hair. Given below are the few known causes of hair loss or thinning hair.

  • Androgenetic alopecia: This term is used to define female or male pattern baldness. It’s a genetically-related issue and makes men lose the hair from the crown and temples of their heads. For women, their hair will become thin all over their heads.
  • Telogen effluvium: When your hair remains in the natural shedding phase on the hair growth circle, your hair will fall though it’s a temporary condition. Telogen effluvium could result from severe stress, childbirth, thyroid problems, surgery, and rapid weight loss.
  • Anagen effluvium: This is experienced during the anagen (growth) phase, where people rapidly lose more hair. It affects the head and can extend to eyelashes, eyebrows, and other parts of the body. Chemotherapy, autoimmune disease, radiation, and fungal infections are known to cause anagen effluvium.
  • Pregnancy: Decreased level of estrogen after giving birth can cause excessive hair loss. However, it’s a temporary condition that can vanish within a year.
  • Other causes: This is an autoimmune condition resulting in hair falling out on the eyebrow, eyelashes, and scalp. Another cause of hair loss is Traction alopecia that occurs when you use tight hairstyles. Certain medications like Warfarin, Accutane, Prozac, Zoloft, Lopid, and beta-blockers may also cause hair loss or hair thinning. Lastly, deficiency of protein, vitamins, and iron may also cause hair loss.
