I was told that if I get Botox in my forehead, I should also get it in the area between my eyes to prevent drooping of the forehead. Is this true?
Preventing Forehead Drooping from Botox?

Don't inject the whole muscle!
The best way to prevent drooping brows when injecting Botox in the frontalis muscle is to leave a cuff or margin of uninjected muscle just above the brows. This should leave you with enough muscle function to prevent any droop and still smooth the upper part of your forehead.
Botox in the up and down oriented frontalis muscle (forehead) can cause drooping of the brows, since the brow lifting muscle is being deactivated.
Injection of Botox into the crow's feet causes relaxation of the orbicularis, a depressor of the lateral brow. Therefore when the crow's feet are is injected, there is a rise in the lateral brows.
Botox to the frown area doesn't counteract central or lateral brow depression caused by forehead injections, but does give a very slight medial brow lift.
Forehead drooping and Botox
If the frontalis (forehead is injected), and there is laxity of the skin, or you use your frontalis to hold up heavy lids, injecting the procerus (a brow adductor that lowers the central brow with the corrugator muscles between the brows) will lessen the risk of brow drop. In young patients, you can inject the frontalis alone, but older patients will get brow drop if some accomodation not done.

If you have decreased tone in your forehead skin and you get Botox than it's likely that your brows will drop. In patients like this we tend to stay away from the lateral brows to prevent complete ptosis or sagging. In fact Botox under the lateral brow will paralyze the orbital muscle and slightly raise the lateral brow.
Botox injected between the eye, the glabellar region, will relax the frown lines between the eyes due to paralysis of the corregator muscle. It will do minimal if anything to prevent brow sagging.
Forehead drooping from Botox
While it is true that botox to the glabellar region and below the lateral brows can counteract drooping from botox injections to the forehead, not everyone who has botox in the forehead will notice drooping of the forehead. In certain cases, botox to the glabellar area, very small amounts injected to the eyebrow areas and below the lateral brows without injection to the forehead can give you a brow lift as well as decrease wrinkling in the forehead because those muscles are no longer working to raise the brows (in reference to Dr. Steinsapir in Los Angeles who developed this microdroplet technique).
Injecting the glabellar area, between the brows, causes less pull of those muscles. Then the frontalis muscle does not have to work as hard to counter the action of the downward pull of the procerus and depressors of the glabella. It is felt that the frontalis muscle is working (tensing) even when you are not actively moving this muscle.
By inactivating the downward pull, your physician does not have to inject as much Botox into the frontalis (forehead). By injecting less Botox, there is less chance of a brow drop (ptosis).
Experienced physicians know not to go too near the brow as this will often cause a brow drop.
Finally, this stresses the need to return to your physician two weeks after adminsitration. At that time any forehead lines can be easily dealt with.

If you don't inject the Botox close to the eyebrows, in the forehead, the eyebrows shouldn't drop. Typically staying 2 finger-widths above the eyebrows to start should do the trick.
