Does caffeine shampoo really work for menopause? Should I use a caffeine scalp serum or a shampoo? Can I just drink more coffee??

In this article, we will dive deep into the scientific research to separate fact from fiction. And we will provide you evidence-based insights on the effectiveness of caffeine for hair regrowth.

Key Takeaways – The Short Version

Caffeine has been proven to reduce hair loss / hair shedding. Caffeine will not regrow hair. It should form a part of hair loss and hair regrowth strategy.

Best paired with a regrowth product such as topical Minoxidil for maximum effect.

Products containing more than 1% caffeine are likely to be effective – but very few products state the percentage of caffeine they contain. Jump to Flo Hive picks HERE.

Why study caffeine for hair growth?

Caffeine, derived from plants like coffee and tea, is a well-known stimulant that has various effects on the human body. Its primary function is to improve focus and endurance. Researchers have also explored its potential impact on hair.

Drugs like Minoxidil enhance hair growth by increasing blood flow to the scalp.

Caffeine is a vasodilator. But caffeine also impacts metabolism and cortisol levels. This is why researchers have investigated whether caffeine could promote hair growth. Caffeine has far-reaching effects throughout the body.

Drinking coffee and the effect on hair health

The effects of caffeine on hair health are not straightforward. On one hand, caffeine has some positive impacts on hair growth, but on the other hand, it can also have negative consequences. Let’s explore the positive and negative effects of caffeine on hair health in more detail.

This bit is super nerdy – get your geek on or keep scrolling!

1. Positive Effect: Improved Vasodilation

Caffeine has been found to improve blood flow to the scalp and hair follicles. This improvement in blood flow is because caffeine blocks the enzyme phosphodiesterase. This enzyme is involved in vasodilation. By blocking this enzyme – caffeine increases vasodilation and improves blood flow to hair follicles.

However, it is important to note that the relationship between blood flow and hair loss is still not fully understood.

While reduced blood flow is a characteristic of androgenic alopecia, it is unclear whether it is the cause of hair loss or is a consequence of hair loss. Therefore, while caffeine’s vasodilation seems promising, but its their impact on hair growth is yet to be determined.

2. Positive Effect: Increased Cellular Metabolism

Caffeine also acts as an antagonist to adenosine receptors. These receptors help regulate cellular metabolism and our wakefulness. By blocking adenosine receptors caffeine prevents neural activity from quieting down – leading to increased wakefulness.

But we all knew caffeine perks us up – now we know the it’s an adenosine blocker!

Studies suggest that caffeine may promote cellular metabolism and the utilization of energy in the body. This effect could positively impact hair growth. As impaired cellular metabolism is associated with hair loss. But more research is needed to fully understand the extent of caffeine’s impact on cellular metabolism.

3. Negative Effect: Increased Insulin Resistance

High-dose oral caffeine consumption has been shown to increase insulin resistance in some people. Insulin resistance is a common factor in early-onset androgenic alopecia, and its presence can interfere with the hair growth cycle. Additionally, oral caffeine’s release of free fatty acids can promote hyperglycemia and further exacerbate insulin resistance.

Individuals with a history of insulin resistance or hypothyroidism may want to stop drinking coffee and tea. It could inhibit hair growth. However the impact of caffeine on hair growth through insulin resistance is still being researched. More conclusive evidence is needed.

4. Negative Effect: Impaired Thyroid Function and Skin Quality

Evidence suggests that oral caffeine consumption is associated with elevated cortisol, which can negatively affect hair. Chronic elevation of cortisol can lead to skin degradation around the hair follicles and disrupt the hair cycle. High levels of cortisol can impair thyroid function. Leading to increased hair loss in individuals with hypothyroidism.

It is important to note that these negative effects are primarily associated with oral caffeine consumption. Limited research is available on the impact of topical caffeine on thyroid function and skin quality. If you have a history of hyperglycemia, insulin resistance or hypothyroidism – you may want to reduce your coffee/tea intake.

Women going through menopause tend to have elevated cortisol. Combined with poor sleep – it is understandable to want to drink more coffee. But consider cutting down, for your hair.

Flo Hive Science Scoop

There is growing evidence to suggest that serums can have some positive effects. Multiple studies have shown that caffeine serums and shampoos can reduce hair shedding rates.

But, it is important to manage expectations and understand that caffeine is not a miracle cure for hair loss on its own.

Unfortunately, many studies (over a dozen) used the feedback from the participants to provide the data for how well the product worked. This is not a very reliable method. Using self-satisfaction feedback isn’t a stringent scientific approach and can be unreliable.

Adding to the confusion, many of the studies measured caffeine in combination with other things. Like Minoxidil.

Very few studies simply studied caffeine on its own. Having said that – it does appear that caffeine in combination can yield better results than caffeine alone or Minoxidil alone.

What to look for in your caffeine product

If you are considering using caffeine as a potential hair loss intervention, the strength of the product is key.

Look for products that have a minimum 1% concentration of caffeine – so that you can replicate the science at home.

Our top picks are –

We recommend products and services based on their research backing, as determined by a review of clinical studies. We receive compensation when readers purchase the products or services we recommend.

Combination Therapy: Combining caffeine with other treatments or ingredients may enhance its effectiveness.

Studies have shown that caffeine in combination with Rogaine for Women can yield better results.

Australian visitors please note, you cannot buy Rogaine on Amazon – head to your local pharmacy to buy Regaine.

Long-Term Efficacy: No studies have measured the long-term efficacy of caffeine for hair regrowth. Therefore, you should consider topical caffeine as a supportive treatment rather than a standalone solution for hair loss.

Conclusion – can caffeine work in menopause?

If you decide to incorporate caffeine into your hair regrowth regimen, it is important to manage your expectations.

Caffeine is not a miracle cure for hair loss on its own. But used in combination with other effective topicals it could help manage hair loss.

Caffeine serums and shampoos with the right concentrations can be effective – such as the one by Watermans –

Particularly when used with other ingredients like Rogaine.

Keep in mind that preventing hair LOSS and promoting hair GROWTH are two different things. Caffeine may prevent hair loss.
