Can hair-loss concealers "suffocate the follicle"? What are the potential side-effects?

Suffocating or Clogging Hair Follicles
Do me a favor though - now that you know your ongoing hair loss is not caused by the hair fibers, act to prevent the relentless loss! Don't just wait for it to happen and then expect a hair surgery to "fix" you, because that is not how it works. Hair surgery is best as an adjunct - working WITH therapies like finasteride, minoxidil, LLLT and ketoconazole/zinc shampoos - NOT all by itself! You will look better in the long run and your surgeon will be able to get a better result for you if you keep as much hair as you can in the first place.
Scalp camouflaging agents don't suffocate
Topical keratin based hair fibers are safe. Rarely, they irritate the scalp and rarely some of the dyes cause problems. But these are fairly rare products.
Most individuals who use these products have genetic hair loss - which is a progressive condition. Generic hair loss gets worse over time if it is not treated. A lot of people using topical fibers will notice their hair is getting worse and worse. Not from the fibers, but from the natural progression of genetic hair loss.
We've outlined all the side effects of these topical camouflaging agents in our 2008 paper published in the Dermatology Online Journal. A link is below.
Hope this information helps.
