Ask the Hair Expert: How do I distinguish Hair Thinning from Hair Loss?
“My hair has become so thin. Am having so much hair loss.”
Sounds familiar? You may have heard these words spoken by at least one person in your circle!
Now conceptually, there are finer aspects to these statements. There is Hair Thinning. Then there is Hair Loss. If you understand these aspects scientifically and deal with it in a timely manner, you can save yourself from experiencing and saying the words above!
‘Thinning hair’ and ‘losing hair’ are interchangeably used often. In almost all such conversations what is actually being referred to is the volume of hair - how much are you able to bunch and hold in your hand? This is something we have observed during conversations with our patients. Further, we have received some queries on social media about the difference between the two!
So here we are, back with our ‘Ask the Hair Expert’ series; this time to address your queries on hair thinning and hair loss, to explain the difference between the two and help you tackle your concerns right.
You asked: "Is hair thinning different from hair loss? How do I know if my hair is thinning or if am losing hair? Is reduced hair volume not the same as hair thinning? What can I do to stop my hair from thinning?”
Here’s the answer from the Hair Experts.
Hair Thinning and Hair Loss are two related but different concerns!
A Trichologist can help you understand their meaning, your hair & scalp condition and guide you best on how to keep your hair healthy.
So, let’s begin by understanding what each of these captioned terms mean. We will then discuss common causes, symptoms and what you can do to control the problem.
What is Thinning of Hair?
Thinning of hair actually refers to an earlier stage of hair loss. This is when the hair shaft, individually, starts to grow thinner and finer in diameter with each hair cycle. It is a progressive disorder that is seen in both men and women. Referred to as Male Pattern Thinning (MPT) or Female Pattern Thinning (FPT), hair thinning happens in both, but the pattern in which the hair thins (and is lost, if ignored!) is different.
In the case of MPT, the pattern is characteristically U-shaped. It starts with thinning on the crown or a receding hairline, which advances to thin the top of the head. In the case of FPT, thinning is seen in the fronto-vertex (centero-parietal) region (atop of the frontal region). The frontal hairline is spared in most cases.
When hair thinning progresses, unattended, it reaches a point where the hair shaft becomes so thin that it becomes ‘vellus’ (hair that is very light, short and superfine...invisible to the human eye even).
What about Hair loss?
When MPT or FPT is observed, and not attended to, over a period of time, it leads to permanent hair loss.
Thinning, which is referred to as Androgenic Alopecia is always irreversible and has to be distinguished from hair fall. Hair fall could be when hair sheds from its roots or hair breakage from the shaft. Hair fall is mostly reversible with a course correction.
Androgenetic/ Androgenic Alopecia is perhaps the most common form of Alopecia that affects both men and women. MPT and FPT are forms of this condition. It relates to the genetic structure and hormonal activity in the body.
Hair thinning, MPT or FPT, over a period of time, progresses, and in some may even lead to baldness.
