Permanent No. 0 Strong is specifically formulated for natural, thick or particularly resistant hair, which requires greater holding power to maintain the shape of the curl in a lasting way. Thanks to its formula enriched with Keratin and Glycerin, it protects the hair fiber during the entire technical process, ensuring a uniform wave without damaging the hair structure.
Its intense action makes it possible to work safely on even the most difficult hair, giving body, elasticity and shine to the final curl. This professional formula, combined with more than 70 years of Arual experience, makes this perm an essential tool in salons for demanding technical work. Characteristic floral aroma.
Wash the hair and towel dry it. Apply the Permanent No. 0 Strong on each curl. Leave on for about 20 minutes, always adapting the time to the professional’s criteria. Rinse with plenty of water and towel dry again. Finish by neutralizing with Arual Neutralizer.
What type of hair is the No. 0 Strong Perm indicated for?
It is formulated for natural, thick or especially resistant hair that requires a more intense action to form long-lasting curls.
What is the difference between Permanent No. 0, No. 1 and No. 2?
The main difference is the level of strength and the recommended hair type:
Does the No. 0 perm damage the hair?
No. Thanks to its formula with Keratin and Glycerin, it protects the hair structure during the process, maintaining hair hydration and elasticity.
How long should it be left on?
The standard time is 20 minutes, although this can be adjusted depending on professional diagnosis and hair resistance.
Can it be used on previously treated hair?
It is not recommended for use on sensitized, bleached or chemically straightened hair. For these cases, we recommend Permanent No. 2 Smooth.
Does it need neutralizer?
Yes, Arual Neutralizer should always be used after rinsing to fix the curl shape in a safe and long-lasting way.
Keratin: essential hair protein that acts as a protective shield during the chemical process. It fills in hair fiber fissures, providing strength, elasticity and resistance. Thanks to its repairing action, it prevents breakage and keeps hair flexible and healthy even after the technical treatment. Ideal for hair previously sensitized by coloring or bleaching.
Glycerin: moisturizing ingredient of vegetable origin that intensely hydrates the hair during the waving process. Helps retain moisture inside the hair fiber, preventing dryness, frizz and stiffness. Improves hair manageability and elasticity, leaving curls soft, defined and visibly healthier looking.
