How much filler is usually put in a forehead that lacks volume?

For the most part fillers are reserved to correct volume loss in the mud and lower face as well as temple area

The forehead gets more hollow as we get older and does cast shadows.
Very fine fillers can be used to volumise the area. The temples and forehead can be treated with filler.Antiwrinkle injections can be used to reduce lines and wrinkles
Laser and energy based devices can be used to improve skin quality also
It is considered to be a high risk area and should only be treated by an experienced physician

There's absolutely nothing better than the person's own fat when it comes to treating a forehead that either has sharp ridges or is lacking roundness. Otologous fat provides a patient with permanent and natural results. Good luck from New York City

When treating forehead volume loss, I usually use 1 (1 mL) syringe of Restylane. In some cases, I will dilute the Restylane with bacteriostatic saline to make it easier to spread along the frontal bone. 

Foreheads can vary a lot!  The temples especially, can take a large amount of filler to volumize properly.   Most people will need one to two syringes, even 3,  per side.  The forehead itself is a little trickier because too much volume here can look really bad.  I wouldn't do more than one syringe at a time and build up slowly to get the best result.  Keep in mind swelling can be an issue and things will probably look worse before they get better.
Hope this helps!

Hello and thank you for your question. Dermal fillers can successfully address forehead volume loss by resupplying the skin with hyaluronic acid. Popular filler brands for targeting the forehead include Juvéderm and Restylane. Forehead wrinkles, however, can be eliminated using Botox injections. If you are experiencing both a lack of volume and forehead wrinkles, your best treatment approach may be a combination of Botox and fillers.
