I have seen a few of these hairlines that almost touch the eyebrows. I saw one that was solid at about 1.5cm above the eyebrows. Usually, if the hairline matures, these juvenile hairlines will disappear with age. It could take until 29 years of age. In some ethnic cultures like Indians, hairlines this low are more common, and some men will maintain such a hairline into adulthood as they never develop a classic mature hairline. This is rare.
Very Low Dose of Finasteride (Less than 0.25mg)
Dear Dr Rassman,
Have you had any patients who have taken very low doses of finasteride (i.e. less than 0.25mg)?
I am not keen to take propecia because I’m concerned of the effects to my internal body chemistry but would also love to keep my hair for longer. I have had issues with my sex drive previously and do not want to mess with my hormone balance too much as a man still in my 20’s. Another reason being that I’m an athlete and want to be at my peak physically. I’ve read a lot about how finasteride affects the hormones, particularly the obvious reduction in DHT but also the decrease in free (not total) testosterone and the rise in estrogen.
Then I read this forum post: Hairlosstalk.com
It seems that taking a dose as low as 0.05mg is enough to lower scalp DHT considerably while keeping 20% more DHT in the blood. Like the original poster in the forum thread who is considering crushing a pill and measuring smaller doses – this prospect is more appealing to me. If I could just lower my blood DHT by 40-50% instead of 70% then surely my hair would still get some benefit and I would be able to keep my hormones at a more normal level. I have ruled out taking 1mg but am really curious about taking 0.05mg if only I could just measure it accurately each time (I wouldn’t want to take fluctuating dosages each day).
It makes me wonder why propecia isn’t available at a much smaller dose (0.05mg or 0.1mg)
Could you comment please? I’d very much appreciate it. Thanks for such an informative blog.
Propecia (finasteride) at 1mg was determined to be the ideal dose for treating hair loss. Lower doses do work, but how low? I’ve said that 0.5mg produces 80% of the benefit, and 0.25mg probably give 50% of the benefit. I don’t have a clue about lower dosages.
But by dosing the 1mg level, it is the most effective treatment level to use… so why dose lower unless there are significant side effects?
Very Irregular Periods a Cause for Female Hair Loss?
Hello there….I am a 29 year old female experiencing frontal and temporal hairloss. I am upset and not sure what to do. I have VERY irregular periods. I may have one 1-2 times a year. Will this cause hairloss? I know a decrease in estrogen will cause it, but I am young and wonder if a very rare period would contribute to it. I have had my thyroid checked and it was ok. Not sure what causes the irregular periods either. I would greatly appreciate a reply to help my questions. I am a nursing student who will be graduating this coming May and would like to look nice for pictures. Thank You
There may be no relationship between your hair loss and your periods. There are conditions like Polycystic Ovarian Syndrome (PCOS), where infrequent periods and hair loss go together. You can see this at 4woman.gov or PCOSupport.
I am not suggesting that this is what is wrong with you, but the diagnosis of female hair loss is complex and requires a complete examination by someone who can evaluate your periods and your hair loss in partnership with you.
Very High Level of Tin in Hair Samples
I had a hair analysis due to thinning hair. I am a 57 female who is menopausal. My report indicated a very, very high level of tin in my hair samples. Good, bad or not related to hair loss? Thank you.
There is no clear relationship between tin levels and hair loss to my knowledge. I would want to know why your tin levels are high and have a doctor find out if it is impacting any organ system in your body. High tin levels could be toxic.
Very Early Balding
I have a doubt. I am 20 and my hair was fine until now,but I feel that my hair is not that dense as it was when I was 10 or 12. Although my hairline is not receded, my dad is bald. Is this a sign of balding or it is natural for eveyone. Also I shampoo my hair once every 3 days with a mild shampoo. Does this have any effect?
A good thorough examination of your scalp with high magnification may show if the early signs of balding have begun. If they have, preventative treatment with Propecia may be indicated. There is no certainty that you will follow your father’s hair loss pattern, but it is a good idea to keep a close eye on it with a good doctor advising you. Shampooing once every three days, once a day, several times per day, or once a year will probably not impact your balding pattern.
Vegetarians, Nutritional Deficiency, and Hair Loss
I am 17, male, and have been loosing the hair in the front of my head for about a year and a half now. I do believe during that time I had used a hair product I was allergic to, as I had a sore scalp in some ares. But I have discontinued it’s use, and was wondering:
- how normal (or not normal) it is to begin having a receding hair line at 16 years of age?
- being a vegetarian, could it be a nutritional deficiency?
- in other answers, I have seen you mention “normal ‘maturing’ hairline development”, or something of the sort. What IS a ‘maturing’ hair growth pattern?
- could masturbating or not exercising affect that, and if so, in what way?
- Yes, a receding hairline can start at 16 years old. Normal? That depends on the person’s genes.
- If you do not have a balanced diet and have a nutritional deficiency, you can thin or lose your hair — this has nothing to do with meat-eaters or vegetarians.
- You should get your scalp mapped out for miniaturization to determine when it is a receding hairline vs genetic hair loss. See Maturation of a Hairline — Moving From Juvenile to Mature for more on the maturing hairline.
- Neither masturbating nor exercise will cause you to lose your hair.
My best advice for you at this point is to see a doctor who can develop a Master Plan for your balding problem and work with him/her, as hair loss is a serious business.

Various Researchers Blame Hair Loss on Different Genes?
Dear Doctor,
I’ve just been reading about your info from Amsterdam.
In addition to this, I was wondering if you in the nearest future see any new drugs against baldness?I’ve read about some new test.
1) Some Japanese researchers blame the Sox21 gene for baldness.
2) Some researchers blame the wnt gene for baldness.
3) Some researchers blame the P2Y5 gene for baldness.Because of my research for hope of any new treatments, I’ve become confused. All these different tests and scientists blame different genes for baldness. Can there really be so many genes, which cause baldness? And where does this leave Propecia, if all this new research blame something else then just DHT for baldness?
I hope you understand my wondering mind.
Best regards.
There are many, many genes for balding and only some have been recognized. A few on the X chromosome have been highlighted by the company HairDX, but genes are constantly being found on chromosomes beyond the X chromosome. Genetic hair loss is very complex (not like the eye color of the fruit fly) and it is the many genes that make the discovery of an effective new drug. Propecia just blocks the DHT hormone and does not address the various genes and approaches you asked about above.

Various Drug (Finasteride, Spironolactone and Recently Dutasteride) Used (From Reddit)
As a clinical scientist, I am not clear about your results. I would suspect that if there is a change and you have been on finasteride for a long time until you switch to dutasteride 1 month ago, that the benefits you see are related mostly to the finasteride and not either the dutasteride or the spirinolactone. This is important information for the readers, listening to an expert address your results. I wish you had comparable pictures because the longer hair makes a huge difference in the appearance, and although it does look like there is hair where there was none before, the results may not be as dramatic as you may think they are.
My progress over the past year. Still thin in spots, but overall I am happy. from tressless

Value to Saw Palmetto in preventing hair loss?
I have recently started oral minxodil, are there any adverse effects to combining saw palmetto and OM? Would I see no change or could I possibly see improvement with them in tandem?
Saw Palmetto has no value as a DHT blocker and, thus, in preventing hair loss.
