Neutralizing the hair after a permanent wave helps to rebalance the pH level of the hair, which is disrupted during the perming process. This neutralization step also stops the chemical reaction of the waving lotion and helps to ensure that the hair remains in its desired shape after the perming process.

When was Permanent Waves created?
Permanent Waves was created on 1980-01-01.
What waves need a medium and which don't?
Mechanical waves, such as sound waves and ocean waves, require a medium (solid, liquid, or gas) to propagate. Electromagnetic waves, including light waves and radio waves, do not require a medium and can travel through a vacuum.
What waves need a medium to travel in?
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
Waves that do require a medium are called?
Sound waves, they need a medium to vibrate.A2. Earthquake waves and other mechanical waves also need a medium for their transmission.Ghv. Tsunamis are a type of mechanical wave, which is the kind of wave you're looking for.
What are three waves that need a medium?
Sound waves: Sound waves require a medium, such as air, water, or solids, to propagate because they rely on the vibration of particles to transmit energy. Seismic waves: Seismic waves, generated by earthquakes or explosions, also need a medium like rock or soil to travel through. Ocean waves: Ocean waves need water as a medium for their motion and propagation, as they are driven by the energy transferred from the wind to the water's surface.
