Allergen Warnings / Cautions
Professional use is recommended; however, experienced users may apply the product at home by strictly following the provided instructions. A mandatory strand test must be performed 3 to 4 days prior to application, especially on blonde, colored, or sensitized hair. Avoid contact with the scalp. For blonde or fine hair, always use lower iron temperatures (up to 350°F / 180°C) and fewer passes to prevent damage. Do not apply to children, pregnant women, or lactating women. In case of contact with eyes, rinse abundantly with water. If irritation occurs, discontinue use and seek medical advice.

FAQ
Is the Let Me Be Single Step Sealant compatible with other chemical treatments?
It is not compatible with Henna (Henê), Ammonium Thioglycolate, Hydroxides, or Guanidine. Always perform a strand test to verify compatibility with your hair's history.
Can I apply this treatment on the same day as highlights or bleaching?
No. We recommend applying the sealant first and waiting at least 30 days before undergoing any other chemical bleaching or highlighting procedures.
How long do the smoothing and alignment results typically last?
The durability depends on the hair type and maintenance routine. On average, the smooth effect and volume reduction last between 1 to 2 months.
Can I retouch my hair color after using this treatment?
Yes, color retouching is possible. However, we recommend using a developer with a maximum of 20 volumes. Avoid 30 or 40 volumes to protect the hair fiber.
Does this product require a special pre-wash shampoo?
No, this is a single-step formula. If the hair is free of heavy oils or styling residues, you can apply it directly. Otherwise, a simple wash with a daily shampoo is sufficient.
