5 units of botox in hairline 2 weeks ago. Will hypertropic corregator muscles go away? Will I have more permanent lines?

Yes, once Botox results resolve (around 3-4 months), your face will go back to normal. In the mean time, venus legacy treatments can soften results. See an expert. Best, Dr. Emer

The Botox in the high forehead will not affect the corrugators. They will not go away. Perhaps you can try an alternative neuromodulator like Dysport or Xeonim. Speak with your injector, I'm sure they can help.Best wishes, Dr. ALDO 

It would be great if you can send some pics!  Botox works.  I am not sure what you mean by rare reactions.  The corregator muscles will relax with the proper placement of Botox.  I am not sure where the 5 unities was placed.  Botox is not "causing" your lines, it does not posses the ability to do so.  So, do send some pics.

You must be very sensitive to Botox, 5 units at the hair line usually doesn't cause very pronounced frown lines. You may want to make sure that the Botox you got is original American made and distributed by US Allergan. Sometimes Botox shipped from outside of US may not be in the refrigerator for longer transport and it can make bacteria multiply, therefore 5units may not be 5, but much more. Anyway, results and side effects should start weaning off within 3-4 months. Alternatively you can have small amount of Botox injected into your corrugators to loosen them up now.
Good luck!

I am not sure what caused the issue but be assured that all side effects of Botox are temporary and will go away completely although it make take a few months

To give you the most precise answer more information and details would be helpful.  Five units of Botox is an extremely low dose spread across the hairline and may have been attempted in order to raise your brows.  Perhaps this has created excessive horizontal wrinkling from your frontalis muscle but it would not be expected to enhance your corrugator vertical lines.
Botox seems in my experience to peak in its strength at approximately two weeks then back off slightly so you may notice some improvement over the next couple of weeks.  The good news is that the results are temporary and should dissipate within 3 to 4 months for most patients.  I hope that this provide some comfort for you.  Best wishesJon A Perlman M.D., FACSDiplomate, American Board of Plastic SurgeryMember, American Society for Aesthetic Plastic Surgery (ASAPS)Beverly Hills, California
