Hair Regrowth Cycles

Dear Dr. Rassman,

I am a 43 year old lady with increased hairloss usually between 150-200 hairs a day at the moment.

3 years ago I had two lots of traumas which caused my initial hairloss. After eventually seeing a trichologist and starting estradex lotion (containing minidoxil and phyto hormones)my hairloss reduced this took 3-4 months to see benefit. Initial the estradex made more hair come out which trichologist said normal as the estradex gets rid of the bad hair making room for better quality hair. I was also put on a antidepressant dotheipin 75mg. 12 months ago I stopped estradex, hairloss returned, not that it totally stopped but hair did look thicker. I have started back on estradex about 3 months on side of head but the partening looking slighlty wider on one side so started using estradex along this area for last 6 weeks. Still taking dothiepin 50mg – 75 mg alt days. I have recently started vitamins saw palmetto and pygeum and stinging nettle root. Sure my telogen as increased within a day of taking this vitamin could it be related. Taking high doses off this up to 2000mg. Or do you think its the estradex getting into my system (which contains 5% minidoxil)?

When I woke up yesterday, the birds were chirping and the air was crisp and I had a great day. Today when I woke up the dog was barking and the air was smoggy and I had a bad day. Do you think I had a good day because the birds where chirping or the air was crisp? Do you think I had a bad day because the dog was barking and the air was smoggy?

Your guess is as good as mine.

There’s too many variables and no direct proven relationships in the information you provided. It is normal to lose 100+ hairs a day. For most normal people, the regrowing hair will start at about the same time as the hair is lost so that the total hair count of hairs growing on the head stays constant. If you do the math, 100 hairs lost per day is about 109,500 hairs in three years (36,500/year) and that is the normal adult hair population. The hair cycling we have discussed before on this web site, is responsible for the fall out and the regrowth that is every person’s normal. The average growth cycle is 3 years for most people, so that means that in three years, most people replace 100% of the hairs on the head with new hair, one day at a time.
