Q & A
What is the main topic of the 'Hair Loss Show' episode featuring Dr. Russell Nudson and Dr. Vicam J Aash?
-The main topic of the episode is the discussion of side effects of minoxidil, specifically comparing topical minoxidil with oral minoxidil.
In what forms is minoxidil commonly available in Australia according to the transcript?
-Minoxidil is commonly available in Australia as a topical liquid or foam, and it can be obtained over the counter without a prescription. There is also an oral tablet form which requires a prescription.
What was the original purpose of minoxidil before it was used for hair loss treatment?
-Minoxidil was originally used to treat high blood pressure, and its side effect of general hair stimulation led to its use as a hair stimulant.
What is contact irritant dermatitis and how is it related to the use of minoxidil liquid?
-Contact irritant dermatitis is a skin reaction that can occur in a small percentage of patients using minoxidil liquid, potentially due to the propylene glycol in the formulation, causing an itchy scalp and other discomforts.
Why was a foam version of minoxidil developed?
-The foam version was developed to address complaints about oiliness and greasiness associated with the liquid form, especially for women, and to potentially reduce the occurrence of contact irritant dermatitis.
What is the difference in absorption time between the minoxidil liquid and foam?
-The minoxidil liquid absorbs in about 60 to 90 minutes, while the foam absorbs in just 10 minutes.
What are some side effects associated with the oral form of minoxidil?
-Some side effects of the oral form of minoxidil include hair growth on the face in women, palpitations, migraine aggravation, and weight gain due to water retention.
Why is it important to apply minoxidil on the skin and not on the hair?
-Applying minoxidil on the skin ensures better absorption and effectiveness. It also helps avoid the side effect of greasiness or oiliness of the hair.
What is the significance of the 'monox shed' mentioned in the transcript?
-The 'monox shed' refers to the initial shedding of hair experienced by some users of minoxidil. It is considered a positive sign as it indicates that the user is responding to the treatment and new hair growth is being stimulated.
How does the doctor in the transcript suggest dealing with side effects from topical minoxidil?
-The doctor suggests starting with a lower dose of oral minoxidil if side effects from topical minoxidil occur, and then gradually increasing the dose while monitoring for any issues.
What misconception about minoxidil does the doctor address in the episode?
-The doctor addresses the misconception that minoxidil stops working after 12 or 18 months. He explains that it's not that the body becomes used to it, but rather that minoxidil may not be fully effective at stopping hair loss progression on its own.
Why is patient compliance important when using minoxidil, according to the transcript?
-Patient compliance is important because if patients do not enjoy using the topical product or find it difficult to remember or fit into their schedule, they are less likely to use it consistently, which can affect the treatment's effectiveness.
