PLÁSTICA DOS FIOS CAFÈ Keratin by Royal Cosmeticos, 1 L
Tested Hair Profile
- Ethnic hair type with porous structure and high density.
- Gray hair: 0%.
- Colored every month with home hair dyes, approximately one tone lighter than the natural base.
- No previous chemical salon procedures.
- Dry ends caused by home flat-iron use and lack of regular mask care.
- Damage level: stage 2.
- Curly, very thick and very dense hair.
Preparation and Procedure Protocol
The shampoo performed very well: neutral scent, thick texture and strong foaming. The hair was shampooed twice, then dried with warm air.
The formula was applied 1 cm away from the roots. Processing time was 20 minutes. After processing, the hair was dried with cold air and flat-ironed at 230 °C with 12-15 passes, until the formula fully evaporated. The hair was left to cool for 20 minutes, rinsed with water, treated with Novex Infusão de Colágeno mask for 10 minutes, rinsed again and finished with a blow-dry.
Formula Behavior During Application
- Consistency: creamy and fluid.
- Application: easy to apply and distribute through the hair.
- Consumption: high because of the fluid creamy texture.
- Absorption: high, with no heavy residue on the surface.
- Scent: mild, but it may irritate the client's eyes. For an experienced stylist, the scent is barely noticeable.
- Steaming: demanding. Around the 10th pass, the formula evaporates to a loose, dry finish, so at least 10-12 passes are needed.
Result After Rinsing
After rinsing, the hair does not keep an unpleasant odor. There is only a light, delicate and barely noticeable coffee trail. The formula controlled frizz well and delivered a clearly smooth finish.
- Straightening quality and power: 100 out of 100.
- Frizz control: achieved.
- Shine: +100.
- Nourishment: 100.
Stylist's Comment
Excellent product, truly 100%. Straightening power is 1000%. Shine +100, nourishment 100.
Cons
The main downside is high product consumption due to the fluid creamy consistency. This should be considered when working on very dense, thick and porous hair.
Conclusion: Royal Plástica dos Fios Café is a strong professional keratin treatment for dense, porous and curly hair when maximum smoothness and high straightening power are required.
