The most obvious of the stages of hair loss is a noticeable change in your hairline that you can clearly see. Baldness often begins in the hairline, with the flat or mildly receded hairline you previously had turned into a more obvious M-shaped hairline — basically, bald with hair on sides.
The Ludwig scale defines three broad stages of hair loss. In stage 1, the hair on the top of the head begins thinning. In stage 2, the scalp starts to become visible. In stage 3, all of the hair at the crown may be lost, resulting in baldness.
The first signs of clinically significant balding appear. The hairline becomes deeply recessed at both temples, resembling an M, U, or V shape. The recessed spots are completely bare or sparsely covered in hair.
The easiest way to determine if your hair is fine or thin is to look at the width. Compare a piece of hair to a piece of thread. If you find that the hair is smaller than the thread, chances are good your hair is fine.
Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
It usually takes 15-25 years to go bald, but can be quicker. Typically, at first the hair begins to thin (recede) at the sides (temples). At the same time, the hair usually becomes thin on the top of the head. A bald patch gradually develops in the middle of the scalp.
At what age do people typically start to lose their hair? Hair loss can start as early as your teenage years or might not occur until you're well past retirement. Generally, people begin noticing signs of hair loss in their 30s and 40s. More significant hair loss often happens when people reach their 60s and beyond.
Stage 2: There's slight hair loss near the skin between your ears and forehead (temples). Stage 3: You have deep hairline recession around your temples, and your hairline may have an “M” or “U” shape. Stage 4: You have very deep hairline recession and a loss of hair at the top of your head (crown).
Thinning hair can grow back depending on what caused it to thin in the first place. People who experience thinning hair due to nutrient deficiencies, stress, pregnancy, and other nongenetic reasons could experience regrowth. If you're experiencing new hair loss or hair thinning, it's best to consult your doctor.
When to see a doctor. See your doctor if you're concerned about how much hair you are losing every day. A gradual thinning on the top of your head, the appearance of patchy or bald spots on your scalp, and full-body hair loss are signs that there may be an underlying health condition.
Many men wonder whether they need to pursue treatment to reverse the effects or if they can grow the hair back on their own. Although hair re-growth may be possible, you should also know when to seek professional help. If the reason for thinning hair is genetics, it will not grow back on its own.
Seasonal shedding often occurs during the fall months, such as September and October, and at some point in the spring, like April and May. This timeline often coincides with the second half of the hair growth cycle, where more hairs are shed.
If you can easily see your scalp through the hair, it's thin. If you can't, it's medium or thick.
Chronic stress has also long been linked to hair loss, but the reasons weren't well understood. Hair growth involves three stages. In growth (anagen), strands of hair push through the skin. In degeneration (catagen), hair ceases to grow, and the follicle at the base of the strand shrinks.
How Do I Know If My Hair Is Falling Out Due To Stress? More than 100 strands of hair clogging your shower drain or on the hair brush is a sure shot sign of hair loss. In telogen effluvium, you will notice hair thinning on the scalp. With alopecia, you may notice bald patches of hair on the scalp.
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
"Sudden thinning hair can be a symptom of anemia (low red blood cell count), hormonal issues especially related to events like pregnancy, or a thyroid disorder, which are all very common in women," says Dr. Peredo.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
Telogen hair, or 'resting' hair, comprises around 15% of the hair on a person's scalp. Periods of elevated stress can lead to this hair being temporarily lost, contributing to a visibly thinner scalp and hairline.
