Hair Shedding vs. Hair Loss: How To Spot The Difference, According To The Pros

Have you ever rinsed out your shampoo to see more than a few strands go down the drain? While it's easy to jump to conclusions when this happens, you should find peace knowing that each person does lose 50 to 100 hairs a day on average. So a few hairs is to be expected—even if it looks daunting. 

"Hair shedding refers to a condition known as telogen effluvium1, when the hair sheds more than usual," board-certified dermatologist Marisa Garshick, M.D., FAAD, tells mbg. "On the other hand, hair loss often refers to a state when something stops the hair from growing," Garshick says. 

As mentioned above, 50 to 100 hairs a day is a normal range of shedding. So if you pull out a few hairs when you rinse out your shampoo or run a brush through your strands, there's no reason to panic. 

Once you begin to lose substantially more hair throughout the day, you may be experiencing excessive shedding. As Garshick says, "Excessive hair shedding may occur as a result of certain physical, emotional, or psychological stressors on the body."

The shedding generally occurs six to 12 weeks after a distressing event or time period, says consultant trichologist Anabel Kingsley.  

Why might you be shedding more than normal?

Increased hair shedding can quickly lead to hair loss, so it's important to keep a mental note of how much hair you're losing if you suspect an increase in shedding. Every time you feel a clump of hairs come out, take note of about how many and what triggered the hairs to come loose. 

For example, ask yourself: Were you pulling on your hair? Just brushing through it? Maybe rinsing out your conditioner? Over time this will provide insight into your hair shedding patterns. 

An additional caveat: If you don't brush or wash your hair daily (like many with curly hair don't), you may notice much more hair than 50 to 100 stands once you do brush or wash your hair.

Causes of hair loss

As you can see, there isn't just one type of hair loss. Each form calls for different treatments and interventions, so it's extremely important to identify the root cause of the hair loss; otherwise, you'll be chasing a solution to a problem you may not even have.

"For example, if your hair loss is not due to a nutritional deficiency, then taking a nutritional supplement isn't going to be effective," Kingsley explains. 

Keeping up with regular scalp care is essential to encourage growth and reduce hair shedding and loss. As a rule of thumb, treat your scalp more like your face than you do your strands—exfoliate weekly and always replenish hydration.

Scalp massages may seem like a pure indulgence, but studies have shown that this practice can significantly affect the health of your scalp and, in turn, improve the appearance of your hair as well. 

In fact, in a 2016 study, a small number of men received a daily four-minute scalp massage. At the conclusion of the study, the investigators found an increase in hair thickness3. A more recent 2019 study found that of the 300 or so participants who followed a specific massage regimen, nearly 70% reported improved hair thickness at the end4.  

Obviously, this is much easier said than done. However, focusing on reducing stress in your day-to-day life will help decrease stress-induced shedding (and better your overall well-being). How you choose to blow off steam will naturally depend on your lifestyle, schedule, and what brings you joy. 

As we mentioned earlier, too little biotin can cause scalp complications and lead to hair loss among other problems. While you can take isolated biotin supplements, there's plenty of combination supplements on the market for healthy hair, skin, and nails that may do the trick and make your investment worthwhile.

If you're not sure what's causing your hair loss, it's best to visit a professional before committing to one mode of treatment. Head to your dermatologist or your local trichologist to get to the bottom of it. Not to mention, Kingsley explains, "Knowing what you are dealing with has a huge impact on decreasing the stress and worry." 

Hair loss and hair shedding are very different, even if they're frequently used interchangeably in conversation.

Daily light shedding is to be expected, but an increase in shedding may be something you want to look into as it can quickly lead to hair loss—another condition with a long list of causes and treatments. If you're unsure if you're experiencing hair loss of some sort, consult a dermatologist or trichologist to get an evaluation.
