Thinning Hair Causes & Facts

“What causes my hair to thin?”

A common family predisposition involves natural, age-related hormonal changes that can trigger hair loss. This is caused by the conversion of testosterone into the toxin Dihydrotestosterone (DHT) and can be inherited from either your mother or your father.

Stress can produce increased levels of testosterone, which converts to DHT and interrupts the hair’s growth cycle. Stress also constricts blood supply through the capillaries, restricting oxygen and nutrient uptake and vitamins to the hair follicle.

Several underlying health issues can cause hair thinning, including a malfunctioning of the hormone-producing thyroid or the natural hormonal changes women experience after pregnancy and during menopause.

Air and water pollutants, chlorine, metals and minerals may be left on the scalp and hair thus contributing to thinning. Pollutants such as pseudo-estrogens and toxins from within our bodies are also a factor.

The hair follicle is incredibly sensitive to changes in the body. Any hormone therapy (including birth control) can contribute to hair thinning, as can steroids, specific chemotherapies, and medication for blood pressure, diabetes, heart disease and acne.

What you eat can plays a significant role in hair thinning. High consumption of animal fats, rapid weight loss and liquid protein diets can result in a lack of amino acids, biotin, iron, protein and zinc— all of which are essential for healthy-looking hair.


Can Caffeine Help With Hair Growth?

Many of us enjoy a nice cup of coffee to start our day and to shake off the early morning cobwebs, but caffeine has other benefits apart from giving you an energy boost. It seems that caffeine might also help with hair growth by stimulating the follicles and strengthening the hair. But don’t start increasing your caffeine intake just yet. We would approximately need to drink about 50-60 cups of coffee a day to get any results, which can be dangerous and not feasible. Let’s explore what makes caffeine a great ingredient in hair loss products.

Thinning Hair Causes & Facts

“What causes my hair to thin?”

Androgenetic alopecia is caused by an increase of the dihydrotestosterone hormone (DHT), that weakens and shrinks the hair follicles in time. A few lab-based studies have found that when applying caffeine to the scalp, the effects of DHT were suppressed. After applying the caffeine, researchers noticed that the hair shaft (the part of the hair that can be seen above the scalp) was elongated, which in turn resulted in wider hair roots1. Another effect caffeine can apparently have, is on the length of the anagen phase of the hair cycle. For those dealing with androgenetic alopecia, the anagen phase, or hair growth phase, is shorter due to the shrinking of the hair follicles. In time this will lead to increasingly thinner, shorter hair. But when caffeine has been applied topically, it seemed to have prolonged the duration of the anagen stage, therefore stimulating hair growth2. Studies have also looked at how caffeine is best absorbed by the scalp and have found that topical application seems to be the best way for caffeine molecules to penetrate the hair follicles. Caffeine-enriched shampoo may work, but the best results will be seen with a leave-on topical solution3, like a hair serum. Our 3D Intensive Diaboost Thickening Treatment, formulated with a blend of caffeine, glycerol and niacinamide, is a leave-in hair serum that promotes thicker hair. This

As mentioned before, drinking coffee won’t have any benefits to your hair. So, don’t think of increasing your caffeine intake and putting your health (and sleep) at risk. Using a caffeine-enriched hair product has minimal risks, but some scalp irritation might appear if you are sensitive to caffeine. It’s important to mention that even though all these studies show very promising results, there is still more research needed in order to understand the effects caffeine has on hair, and especially on conditions like androgenetic alopecia. Most of the studies conducted so far have been performed in vitro, meaning they have been done on human subjects. Hair loss can happen due to various factors so it’s important to identify the cause of the problem before starting any treatment. Nioxin can help you on your journey and make your hair thicker, fuller looking with our dedicated thinning and hair thickening products.


Treatments & Advice

Commencing when a woman’s body begins to produce less estrogen (usually around the age of 50), menopause, can be an emotionally and physically taxing experience, bringing with it a whole host of symptoms ranging from hot flashes to hair loss. 

If you’re aged between 45 and 55 and have noticed a change in your hair pattern (whether that be a decrease in hair density or an increase in finer strands) it might be a sign of menopause.

While thinning hair might eventually result in hair loss, these two situations are not strictly interchangeable.

A lot of menopausal women witness an overall thinning of the hair (as opposed to noticeable bald spots which occurs sometimes with male hair loss) and 40% of women also experience hair thinning post-menopause1.

The majority of hair loss, on the other hand, is genetic. One such example is female pattern baldness, which runs in families and often develops after menopause2.

Whether you’re experiencing hair thinning or a loss of hair, the effects aren’t purely physical. For many women, cutting and styling their hair provides a platform for self-expression; when this is taken away or disrupted by hair becoming thinner or falling out completely, it’s natural to expect a decrease in self-esteem and confidence. 

Perimenopause is the name given to the phase which begins several years before the menopause. Common perimenopause symptoms include:

  • Hot flushes
  • Breast tenderness
  • Low sex drive
  • Fatigue
  • Mood swings
  • Insomnia
  • Thinning hair
  • Hair loss
Some women begin to notice a change in hair pattern during perimenopause. They might find clumps of hair in their brushes and showers or notice some thinning at the crown.

Hair is prone to falling out when there is a drop in estrogen and progesterone, something which is characteristic of menopausal stages. These hormones help the hair growth process run smoothly, keeping follicles firmly rooted to the head. When a drop in these hormones occurs (as it does during menopause) a consequential effect is that hair becomes thinner and grows more slowly. A drop in oestrogen and progesterone also causes androgens (a group of male hormones) to increase in production which, in turn, shrinks hair follicles and may result in hair loss4. Hair loss in women over 50 can also be caused by lifestyle choices, such as stress, illness and poor diet. NIOXIN have put together expert tips for coping with changes in your hair during this difficult stage.

How To Deal With Hair Loss Or Hair Thinning Caused By Menopause

It takes time for hair to regain volume once it has thinned, and it’s not always possible to regrow your hair fully back to what it was once you’ve experienced hair loss. Nevertheless, a mixture of lifestyle changes and on-going treatments and medications can help slow down hair loss and minimize thinning.

1. Style Your Hair Differently

When it comes to styling your hair, opt for a shorter, layered cut to give the illusion of thicker, denser hair.

2. Manage Your Stress Levels

A stressful lifestyle can also have an adverse effect on hair. When our stress levels are not in check, it results in hormonal imbalance and reduced estrogen production, causing mood swings and even anxiety and depression, along with a higher risk of hair loss

3. Exercise

Doing a form of exercise like yoga can help keep stress levels under control and prevent other menopausal symptoms (such as mood swings, weight gain and insomnia) from occurring.

When hormones are balanced, the scalp microbiome thrives and hair growth is supported. The scalp microbiome is the name given to the ecosystem of bacteria on the scalp which help prevent your skin from breaking out

4. Make Some Changes To Your Diet

It’s also important to eat a balanced, nutrient-rich diet when experiencing hair loss during menopause. The following foods play a crucial role in maintaining and restoring hair growth: Whole grains, Fruits and vegetables, Olive oil, Sesame oil, Green tea, Salmon, Tuna, Flaxseed oil, Walnuts, Almonds

5. Limit Your Use Of Styling Tools

Hair dryers, straightening irons and other heat tools can weaken your hair, causing breakage and hair loss.

Drying and breakage can also be brought about by sun damage, meaning that when on vacation, it’s important to wear a hat or sun protection for the hair and the scalp.

6. Take Vitamins For Menopausal Hair Loss

Make sure you increase your intake of protein-rich foods, such as red meat, beans, fish, eggs and milk, as these are full of amino acids. Keratin is a protein made up of amino acids and is the key structural material which makes up hair.

Vitamin C is useful for many things and hair is no exception. Vitamin C (scientifically known as ascorbic acid) enables hair to absorb more moisture. It also acts as an anti-oxidant, protecting against structural damage to hair proteins. (It can, however, strip hair of its dye so if you have colored hair, please be aware of this.)

Vitamin A plays a key component in moisturizing hair and stopping it from becoming brittle.

7. Seek Emotional Support

It’s extremely important to come to terms with hair loss during menopause, whether you expect it to be temporary or permanent.

Discuss your situation with your doctor or trichologist, and with friends.

Join a support group to find others who are experiencing the same thing.

Consider counselling if you feel hair loss is impacting your mental health.

Make some small lifestyle changes and be patient with them – it can take 3-6 months to see a difference.

Recommended Hair Loss Products

While vitamins can certainly help minimize the effects of hair loss during menopause, haircare products, such as NIOXIN’s 3D Care System, can also successfully address the effects of hormonal hair loss and help you regain confidence.

Aiming to amplify hair texture and prevent breakage, the 3D Care System is available in six different variations, depending on your hair colour and the level of thinning you’re experiencing.

The treatment involves a simple three-step system to help you on your way to thicker, fuller hair:

Apply the cleanser, which is designed to rinse away any build-up of sebum and skin debris to leave your scalp in optimal condition. This shampoo for thinning hair is great for menopausal hair loss because it preps the hair and the scalp for the hair thickening treatment.

Next, use the conditioner to provide nourishment to the hair strands from root to tip, something which delivers deep moisture to the hair and scalp and prevents breakage.

Massage the leave-in Scalp Treatment into the roots to refresh the scalp area and provide fuller looking hair.

Many of NIOXIN's other products can be used in combination with the 3D Care System. NIOXIN Diaboost, a leave-in treatment, has been carefully crafted to thicken existing follicles at the roots instantly; the Night Density Rescue promotes hair density and reduces hair loss associated with scalp surface oxidation. Our newest hero product Nioxin’s Anti-Hairloss Serum ; is a leave-on formula that creates a thicker illusion after just one use. It helps to improve the appearance of hair loss after eight weeks, fortifying your stands for a healthier-looking end result.

You should to visit your doctor, or a trichologist, if:

You have any pain or itching associated with hair loss.

Your scalp skin looks red or scaly.

You are losing your hair in an unusual pattern.

You are under 45 and losing your hair (you may be going through premature menopause.
