What Causes Hair Loss or Thinning Hair?

The terms hair thinning and hair loss are often used interchangeably, yet they refer to completely different hair concerns. While it might seem like a matter of word choice, understanding the difference can help determine the best course of thinning and hair loss treatment. It’s normal to lose some hairs throughout the day; in fact losing up to 100 hairs daily is typical (don’t worry – we’re not going to make you count them). However, more could indicate you are shedding more than you ought to be, and can be a sign of hair loss. Hair thinning, however, is when the density of hair decreases, due to brittleness, breakage, and – you guessed it – thinning strands.

Hair loss can happen gradually or suddenly, caused by a variety of factors such as genetics, hormonal changes, medical conditions, or stress. Thinning, on the other hand, is a more gradual process related to ageing, poor nutrition, heat damage, or over-grooming.

But fear not. While both conditions can be distressing, treatments are available which support stronger, healthier-looking hair.

Causes of Hair Loss and Hair Thinning

There are many reasons why hair may begin to thin or stop growing, including:

• Genetics
• Hormonal Changes
• Stress
• Poor Diet and Nutrition
• Ageing
• Medical Conditions and Certain Medications

How to Help with Hair Loss

If you’re experiencing hair loss, several treatments may encourage regrowth including:

Minoxidil (Loniten)

Available as a topical or off-label oral treatment, minoxidil stimulates hair follicles and promotes hair regrowth. This well-studied, effective treatment has been shown to significantly increase hair count compared to a placebo.

Finasteride (Propecia) or Dutasteride (Avodart)

Part of the same medication family, dutasteride and finasteride work in a similar way and should not be taken in conjunction with one another. They work by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone closely linked to hair loss. While not licenced for hair loss in women due to pregnancy risks, these treatments have shown significant effectiveness when preventing male pattern baldness.

Peptides

These short chains of amino acids can be used to encourage hair growth by stimulating hair follicles, improving blood flow to the scalp, and reducing inflammation, all of which contribute to hair loss. Often used as a topical treatment, peptides are a popular option for supporting healthy hair growth.

How to Help with Hair Thinning

If your hair is thinning rather than falling out at the root, the following treatment can help improve hair strength and appearance:

Keratin

Keratin is a protein found naturally within the structure of hair. Using keratin-containing products can help strengthen existing strands and reduce breakage, leaving hair looking thicker for up to six months. While keratin treatments won’t stimulate new growth, they can ensure that hair doesn’t break off as easily, and even repair existing damage to hair.

Collagen

Collagen helps to maintain the structure of the scalp and strengthen the dermis, which supports the hair root. It also acts as an antioxidant, protecting against free radical damage which can cause scalp damage and contribute to hair thinning. Supplementing with collagen may help promote a healthier scalp, and fuller-looking hair.

Caffeine

Applied topically, caffeine increases blood circulation to the scalp, stimulating hair follicles and encouraging growth. It can help deliver nutrients and oxygen to the scalp and hair follicles which are important in hair growth, and may prevent the effects of dihydrotestosterone too, helping to prevent further hair loss.

The Bottom Line

Whether you’re aiming to stimulate hair growth or improve the appearance of thinning hair, the right ingredients and treatments can make a noticeable difference for male pattern hair loss and thinning hair. From medically licensed treatments such as minoxidil and finasteride, to nourishing ingredients like keratin and caffeine, the right approach can help. If you’re concerned about hair loss or thinning, consult with a healthcare professional and find a treatment that works for you.
