Hair Growth Product Recommendations from Dermatologists

Reading time -

Hair is not just a physical attribute; it’s often tied to our identity and self-esteem. So when it begins to thin or fall out, it's natural to feel a sense of panic. But fear not, for science and medicine have made incredible strides in the realm of hair regrowth.

Dermatologists, the experts in skin, hair, and nail care, play a critical role in diagnosing and treating hair loss. In this article, we'll delve into the realm of dermatologist-recommended hair growth products. From the tried-and-true minoxidil to modern laser devices, we'll cover an array of products backed by science to help regain your mane. In the end, we'll also introduce you to Phoenix - a cutting-edge Canadian telehealth service that brings professional healthcare, including hair loss solutions, straight to your doorstep.

What Causes Hair Loss?

Before we dive into the products, it’s important to understand what causes hair loss. Hair loss is a common phenomenon, affecting millions of men around the globe. There are various factors that can cause hair to thin or fall out, including genetics, hormonal imbalances, nutritional deficiencies, stress, or underlying health conditions.


For many, hair loss is written in their DNA. Male pattern baldness, also known as androgenetic alopecia, is the most common type of hair loss in men. It is characterized by a receding hairline and thinning of hair on the crown and is mainly attributed to genetic predisposition and hormones. Female pattern baldness is similar but tends to result in overall thinning rather than a receding hairline.

Hormonal Imbalances

Hormones play a crucial role in hair growth. Dihydrotestosterone (DHT) is a hormone that’s believed to cause hair follicles to miniaturize, which can contribute to pattern hair loss. In women, hormonal imbalances due to polycystic ovary syndrome (PCOS) or menopause can also lead to hair thinning or loss.

Nutritional Deficiencies

What you eat has a direct impact on the health of your hair. Deficiencies in vital nutrients like iron, zinc, and protein can contribute to hair loss. Biotin, a B vitamin, is particularly important for hair health and a lack of it can cause hair to become frail and break.

Stress and Underlying Health Conditions

Stress is a common culprit behind temporary hair loss. This includes physical stress from surgery or an accident, emotional stress, and even some medications. Underlying health conditions such as thyroid problems can also affect hair growth.

Understanding the root cause of hair loss is essential for finding the most effective treatment. In the next sections, we will explore dermatologist-recommended products, starting with Minoxidil, that target various causes of hair loss and promote hair growth.

1. Minoxidil - The Pioneer in Hair Regrowth

When it comes to hair growth products, Minoxidil is often the first name that springs to mind. It has been a stalwart in the battle against hair loss since the 1980s, and continues to be one of the most recommended treatments by dermatologists.

What is Minoxidil?

Minoxidil is an over-the-counter medication that is used to stimulate hair growth and slow balding. Originally developed as a treatment for high blood pressure, doctors soon noticed that patients were growing hair in areas where they had lost it. This serendipitous discovery led to the development of Minoxidil as a topical solution specifically for treating hair loss.

How Does Minoxidil Work?

While the exact mechanisms are not entirely understood, Minoxidil is believed to prolong the growth phase of hair follicles. It opens up potassium channels, which causes more nutrients and blood to flow to the hair follicles. This can lead to thicker and longer hair strands. It’s particularly effective in individuals with androgenetic alopecia.

How to Use Minoxidil?

Minoxidil is available in different forms – liquid, foam, or shampoo. To use, apply the product directly to the scalp, specifically in areas where the hair is thinning. It's important to use Minoxidil consistently, as stopping the treatment can cause hair loss to resume. Please note that while some people may see results in as little as two months, others may take up to four months or more.

Potential Side Effects

As with any medication, there are potential side effects. The most common side effect of Minoxidil is irritation of the scalp. In rare cases, it can cause unwanted hair growth in areas other than the scalp, or exacerbate heart issues in people with existing heart conditions.

Dermatologist Tips for Using Minoxidil

Dermatologists recommend starting with a lower concentration, like 2%, to see how your scalp reacts, before moving to a higher concentration, such as 5%. It’s also advised to be patient and consistent with the treatment, as results take time. Moreover, consulting a dermatologist before starting any treatment is always wise to ensure it’s the right option for your specific case.

2. Finasteride - A Potent Ally in Fighting Hair Loss

After Minoxidil, another highly recommended product by dermatologists for treating hair loss, especially in men, is Finasteride. This prescription medication has been a key player in the fight against male pattern baldness and has helped countless men regain their confidence.

What is Finasteride?

Finasteride is an oral medication that inhibits the action of an enzyme called 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). As we’ve discussed earlier, DHT is believed to be a significant factor in male pattern hair loss, causing hair follicles to shrink and produce thinner hair over time.

How Does Finasteride Work?

By inhibiting the conversion of testosterone into DHT, Finasteride decreases the levels of DHT in the scalp. This allows the hair follicles to recover and produce thicker and healthier hair. Studies have shown that Finasteride can not only stop hair loss but in many cases also promote regrowth of hair.

How to Use Finasteride?

Finasteride is typically prescribed in 1 mg tablets, taken orally once a day. Like Minoxidil, consistency is key. Discontinuing the medication will likely result in the return of hair loss. It is important to consult a healthcare professional before starting Finasteride to make sure it is appropriate for your situation.

Potential Side Effects

Though Finasteride is generally well-tolerated, some individuals may experience side effects such as decreased libido, erectile dysfunction, or changes in ejaculation. These side effects are relatively rare and usually resolve once the medication is stopped.

Dermatologist Tips for Using Finasteride

Dermatologists recommend discussing your medical history and any concerns with a healthcare professional before starting Finasteride. Monitoring the progress is also essential, and taking pictures can be helpful to visually track the changes. It’s also worth noting that combining Finasteride with Minoxidil can sometimes have a synergistic effect, resulting in improved hair growth.

3. DHT-Blocking Shampoos – Cleaning Your Way to Fuller Hair

As you stride towards reclaiming your luscious locks, DHT-blocking shampoos emerge as yet another powerful tool recommended by dermatologists. These shampoos are formulated to combat the hormone DHT, one of the main culprits in pattern hair loss.

What are DHT-Blocking Shampoos?

DHT-blocking shampoos contain ingredients that are believed to inhibit the production or effects of DHT on the scalp. These ingredients often include natural extracts such as saw palmetto, nettle extract, pumpkin seed oil, and ketoconazole, which have shown promise in reducing DHT levels.

How Do DHT-Blocking Shampoos Work?

DHT-blocking shampoos work by incorporating ingredients that either reduce the production of DHT or prevent DHT from binding to hair follicles. By reducing the impact of DHT, these shampoos can help to slow down hair loss and in some cases, promote the growth of new hair.

How to Use DHT-Blocking Shampoos?

Using a DHT-blocking shampoo is as simple as using a regular shampoo. Apply it to wet hair, gently massage into the scalp, and rinse thoroughly. It’s important to leave the shampoo on your scalp for a few minutes before rinsing to allow the active ingredients to penetrate. For best results, use the shampoo regularly as directed on the product label or by your healthcare professional.

Potential Side Effects

DHT-blocking shampoos are generally safe for most people. However, some individuals may experience scalp irritation or dryness. It’s important to choose a shampoo that is free from harsh chemicals, and if you have a sensitive scalp, look for one that is specifically formulated for sensitive skin.

4. Biotin Supplements – Nourishing Your Hair from Within

While topical treatments and special shampoos play a vital role in your hair growth journey, nutrition shouldn't be overlooked. Dermatologists often recommend biotin supplements for individuals experiencing hair thinning or loss, as this essential nutrient is a key player in the health of your hair.

What is Biotin?

Biotin, also known as vitamin B7, is a water-soluble vitamin that's part of the vitamin B complex group. It's crucial for the body's metabolism, helping to convert certain nutrients into energy. It also plays an important role in the health of your hair, skin, and nails.

How Does Biotin Work?

Biotin contributes to the production of keratin, a type of protein that makes up your hair, skin, and nails. Low levels of biotin can lead to thinning of the hair and even hair loss. By supplementing with biotin, you can ensure that your body has the necessary nutrients to produce healthy hair.

How to Use Biotin Supplements?

Biotin supplements come in various forms, including tablets, capsules, and gummies. The dosage can vary, but it's important to remember that as a water-soluble vitamin, excess biotin will be excreted from the body rather than stored. It's recommended to consult a healthcare professional to establish the optimal dosage for your needs.

Potential Side Effects

Biotin is generally considered safe with minimal side effects. However, it's worth noting that excessive intake can interfere with certain lab tests, such as those for thyroid function, and potentially lead to misdiagnosis. Always inform your healthcare provider about any supplements you're taking.

Dermatologist Tips for Using Biotin Supplements

Dermatologists often recommend biotin supplements as a supportive measure in a comprehensive hair care routine. Keep in mind that while biotin can support hair health, it’s unlikely to reverse hair loss on its own. Using it in conjunction with other treatments, like Minoxidil, Finasteride, or DHT-blocking shampoos, can provide a more holistic approach.

5. Laser Hair Growth Devices – The Future of Hair Regrowth

Advancements in technology have led to innovative solutions for hair growth, and laser hair growth devices are at the forefront of this revolution. These devices, often recommended by dermatologists, utilize low-level laser therapy to stimulate hair follicles and promote hair growth.

What are Laser Hair Growth Devices?

Laser hair growth devices use low-level lasers or light-emitting diodes (LEDs) to deliver red light directly to the scalp. This type of therapy is known as low-level laser therapy (LLLT). The devices come in various forms, including laser combs, helmets, and caps.

How Do Laser Hair Growth Devices Work?

Low-level laser therapy works by using photons of light to stimulate the mitochondria in hair follicles. This, in turn, increases cellular energy production and can revitalize shrinking hair follicles. The end result is often a slowdown in hair loss, and in some cases, the promotion of new hair growth.

How to Use Laser Hair Growth Devices

Using laser hair growth devices typically involves placing the device on your head for a set amount of time, usually several minutes, multiple times a week. The exact specifications can vary depending on the device, so it’s essential to follow the manufacturer’s instructions or the guidance of your healthcare professional.

Potential Side Effects

Low-level laser therapy is considered safe, and side effects are rare. However, some individuals might experience mild scalp irritation. It’s important to note that while many people have seen benefits from using laser hair growth devices, results can vary, and not everyone will respond to the treatment.
