Choosing the correct perm strength is essential for achieving long-lasting curls while maintaining the health and integrity of your hair. L'Oréal Dulcia offers different strength levels 0, 1, and 2 so professionals can customize the service based on hair type, sensitivity, and desired curl definition.
Understanding What Perm Strength Means
Perm strength refers to how powerful the formula is in restructuring the hair’s internal bonds to create curls or waves. Using the right level ensures optimal shape without over-processing or causing unnecessary dryness.
Dulcia 0 – For Resistant or Natural Hair
This is the strongest option, ideal for hair that is difficult to reshape.
• Best suited for natural, thick, or resistant hair
• Helps achieve defined curls that hold their structure
• Recommended when hair has never been chemically treated
• Delivers long-lasting, structured results
Dulcia 1 – For Natural to Slightly Sensitized Hair
This is a balanced strength designed for most hair types.
• Suitable for normal or slightly sensitized hair
• Creates soft curls or controlled waves
• Maintains elasticity while providing reliable hold
• Ideal for clients seeking natural-looking movement
Dulcia 2 – For Sensitized or Treated Hair
This is the gentlest formula, developed for delicate hair conditions.
• Designed for color-treated or previously processed hair
• Minimizes stress on the hair fiber
• Produces smooth, soft waves rather than tight curls
• Helps preserve shine and manageability
How to Choose the Right One
Selecting the correct strength depends on your hair’s history and condition, not just the curl you want.
• If hair is thick and untouched → Choose Dulcia 0
• If hair is healthy but manageable → Choose Dulcia 1
• If hair is colored, fragile, or treated → Choose Dulcia 2
• Always assess elasticity and porosity before application
• Professional consultation ensures safer, more predictable results
Why Correct Strength Matters
Using the proper perm strength protects the hair structure while delivering consistent curl formation. When matched correctly, Dulcia allows you to reshape hair safely, creating results that feel soft, controlled, and professionally finished rather than overly processed.
