Understand The 5 Main Types Of Oral Hair Growth Medication + How To Use Them Properly

Oral hair growth medication is one of the most common modern treatments for androgenetic alopecia. These medications primarily work by inhibiting the activity of 5-alpha reductase and dihydrotestosterone (DHT) in the body, which helps prevent hair follicle miniaturization and closure. By slowing hair loss and encouraging new growth, these treatments can help increase overall hair volume. However, there are many different types of oral hair growth medications, and since most function as androgen inhibitors, choosing the wrong one can lead to hormonal imbalances. That’s why careful selection is essential!

Let’s break down the five main types of oral hair growth medications, including how to tell the difference between Propecia, Proscar, Loniten, Avodart, and more. We’ve also included proper usage guidelines—and a surprise at the end for those tackling hair loss!

The 4 Main Causes of Hair Loss: Know Your Enemy to Defeat It

• Androgenetic Alopecia (Genetics, DHT): The most common type of hair loss, it’s linked to genetics and elevated testosterone. DHT, a byproduct of testosterone, attacks hair follicles, causing them to shrink. This results in thinner, shorter hair that eventually stops growing.

• Telogen Effluvium (Stress, Illness, Medication): Stress, illness, or certain medications can disrupt the hair growth cycle, pushing large numbers of follicles into the resting (telogen) phase, leading to excessive shedding or even permanent loss.

• Alopecia Areata (Immune System): An autoimmune condition where the immune system mistakenly attacks hair follicles, causing patchy hair loss.

• Postpartum Hair Loss (Hormonal Changes): After childbirth, rapid hormonal fluctuations—especially elevated DHT—can shrink follicles, leading to temporary hair loss.

Other potential causes include nutrient deficiencies (e.g., vitamins and minerals), scalp conditions (seborrheic dermatitis, folliculitis), and unhealthy lifestyle habits (smoking, alcohol, sleep deprivation).

Common Symptoms of Hair Loss: 4 Early Warning Signs to Watch Out For

Hair thinning usually happens gradually, so it’s important to act early—especially if you have a family history of androgenetic alopecia.

• Thinning at the Crown: A widening hair part or more visible scalp.
• Receding Hairline: Hair loss at the temples, creating an “M-shaped” hairline.
• Diffuse Thinning: Thinning that isn’t limited to the front or crown—can occur all over.
• Increased Shedding & Noticeable Volume Loss: Sudden, excessive shedding is abnormal and a clear red flag.

5. Other Oral Supplements: Biotin, Zinc, etc.

• These support healthy hair growth and are often used alongside prescription treatments.
