A professional smoothing treatment that combines proteins, conditioning agents, and silicones to reinforce weakened hair, align the cuticle, and reduce frizz. Its acidic pH helps seal the fiber, enhance shine, and improve manageability, leaving hair smoother, softer, and more resistant to breakage. The multi-protein complex—comprising hydrolyzed keratin, collagen, and plant-derived proteins—acts by temporarily reinforcing weakened regions of the cortex and improving fiber cohesion, while the cationic agents selectively bind to negatively charged, damaged sites to enhance cuticle alignment and reduce inter-fiber friction.

Knowing your hair’s needs is essential before applying a professional keratin treatment. MEVYS Lemon-Lime Keratin can benefit multiple hair types, but the amount of product, saturation level, processing time, and heat protocol should be adjusted according to hair density, texture, porosity, chemical history, and overall fiber condition (To avoid heaviness or over-coating, do not apply on scalp). Independent of the hair type, start at the hair growth (not roots), while making your way towards the mid section and the ends for proper appliance.
Short Hair: Apply a controlled, light amount section by section, focusing on the fiber rather than the scalp. Distribute evenly through the hair with a fine or medium-tooth comb, removing excess product where needed to avoid over-coating
Why: Short hair has less surface area and often less accumulated damage, so over-saturation can make the hair feel coated or flat. A lighter application allows the keratin, proteins, and smoothing agents to refine the fiber while maintaining natural movement.
Fine Hair: Use a minimal saturation approach. Apply mainly from mid-lengths to ends, keeping product away from the scalp and root area unless the hair is extremely frizzy or chemically compromised. Comb thoroughly to ensure even distribution and remove excess before the heat-sealing step.
Why: Fine hair has a smaller fiber diameter and can be weighed down more easily by silicones, cationic conditioners, fatty alcohols, and emollients. Controlled application helps deliver smoothness, shine, and frizz control without sacrificing volume or body.
Medium Hair: Apply a moderate, even amount from roots-adjacent areas through ends, avoiding direct scalp contact. Work in clean sections and comb through each section to ensure uniform coverage before proceeding with the professional protocol.
Why: Medium hair generally tolerates keratin treatments well because it has enough fiber mass to receive conditioning and smoothing benefits without becoming overly heavy. The multi-protein system helps improve the feel of strength and smoothness, while the acidic pH supports a more refined cuticle appearance.
Normal/Virgin Hair: Use a light-to-moderate application, depending on frizz level and texture. Focus on the mid-lengths and ends, and avoid excessive saturation if the hair is already healthy, smooth, or low-porosity.
Why: Virgin or normal hair often needs refinement, not aggressive correction. Too much product may coat the surface unnecessarily, so the goal is to enhance shine, softness, and manageability while preserving the hair’s natural movement.
Long Hair/Extra Long Hair: Divide the hair into 4 or more sections for better control. Apply evenly from mid-lengths to ends, paying extra attention to older, more porous ends, where dryness, friction, and mechanical wear are usually more visible
Why: Long hair has more cumulative damage because the ends have been exposed to brushing, heat styling, UV exposure, washing, and friction for a longer time. These areas often benefit most from the keratin’s protein blend and smoothing system, which help reduce roughness, improve shine, and enhance manageability.
Abundant (thick) Hair: Work in small, clean sections to ensure complete and even coverage. Apply a more generous amount compared with fine or short hair, but still avoid dripping, heavy buildup, or direct scalp application. Comb through each section carefully to distribute the treatment uniformly.
Why: Thick or abundant hair has higher fiber density, meaning more product is needed to reach all strands evenly. Sectioning is essential so the smoothing agents, proteins, and conditioning system can coat the fiber consistently and deliver a polished, controlled result.
Fragile, Heavily Bleached, or Over-Processed Hair
Fragile, heavily bleached, or over-processed hair requires the most conservative application approach because the fiber is usually porous, weakened, and more reactive to heat. For this hair type, MEVYS Lemon-Lime Keratin should be applied with light-to-moderate saturation, focusing on the mid-lengths and ends while avoiding direct scalp application and avoiding product overload
Why: Bleached and over-processed hair often has a lifted cuticle, reduced elasticity, and uneven porosity. The Lemon-Lime Keratin contains hydrolyzed keratin, hydrolyzed collagen, silk amino acids, hydrolyzed wheat, rice, soy, and silk proteins, which can help the hair feel stronger, smoother, and more conditioned, while ingredients such as amodimethicone, cetrimonium chloride, steartrimonium chloride, glycerin, and cyclopentasiloxane support slip, softness, shine, and frizz control
Who should receive the MEVYS Lemon-Lime Keratin Treatment with a lighter or customized application?
The following hair types may still benefit from MEVYS Lemon-Lime Keratin, but they require a lighter application, controlled saturation, lower heat when needed, and professional assessment to avoid heaviness or over-processing:
Fine hair
Fragile hair
Low-porosity hair
Virgin hair
Heavily bleached or easily weighed down hair
