Aesthetically speaking, few things are as alarming as noticing that your hair is starting to thin. Regardless of the root cause, a drastic change of appearance can make your self-esteem take a hit and cause some serious stress—which can in turn make the problem worse. As with most things, the sooner you tackle an issue, the easier it is to take care of, which is why I spoke to a hairstylist about the best thickening hair serums to help.
Personally, I suffer from a shocking amount of hair loss when I’m under extreme stress. Life changes such as a cross-country move, a difficult breakup, and grieving a loved one have resulted in losing large clumps of hair for months at a time. Every time I see the physical manifestation of stress I’m visually reminded how much the inside affects our outside—they’re all interconnected. And while stress can be common cause of hair loss, it’s not the only reason someone may need help in the hair thickening department.
As master hairstylist at Fox and Jane, Betsy Duggan explains there are many causes for hair loss. They can be as simple and as common as the natural aging process or be the result of a more serious medical issue. She recommends seeing a dermatologist if you notice hair falling out or shedding on your pillowcase in large clumps. Aside from taking supplements, indulging in a scalp massage, and cutting out heat styling, she recommends using a thickening hair serum to help tackle the issue.
Causes of hair thinning and loss include:
- being postpartum
- overly processed and damaged hair
- vitamin deficiency
- stress/mental health issues
- natural aging process
- lack of sleep
- hormonal shifts
- scalp issues
What is a hair serum?
You’ve probably seen a lot of smoothing, shine-inducing serums at your local drugstore and Sephora. While these are great for frizzy hair and heat protection, they don’t actively help to thicken the hair. In fact, many do the opposite by weighing it down and can even contribute to hair loss if you put too much on your tresses. Yikes!
Duggan shares that the best thickening hair serums are less about immediate aesthetic results and more about strengthening and protecting the hair, and supporting thickness long-term. Some of them plump the hair strands and help to add volume to make the hair look thick and full, while others are full of nutrients and antioxidants to help promote hair growth. Many work in tandem to achieve both kinds of results, ideally these are the ones you should be purchasing.
