Organic straightening solution designed for dark, thick and coarse hair. This advanced formula smooths, nourishes, and strengthens hair, reducing frizz and volume while enhancing softness and shine. Enriched with botanical extracts and essential oils, it provides deep hydration and long-lasting results.

✔ Suitable for dark, thick and coarse hair
✔ 3 to 5 applications per bottle (varies by hair length)
✔ Instantly smooths and aligns hair strands
✔ Results last up to 4 months with recommended aftercare (Protein Hair Care Kit)
✔ No waiting period – wash hair immediately after treatment
✔ Requires a minimum 3-month gap between treatments

We recommend doing a strand test at least 3 to 4 days before.

Shake the bottle well before use.

Wash hair with Let Me Be Shampoo massaging into a lather. Rinse thoroughly. Repeat 2 to 3 times until hair is completely clean.

Dry hair 100% using a hair dryer.

Apply the product to dry hair using a brush. Do not apply on scalp. Use gloves.

Leave product on hair. Waiting time depending on the texture and condition of your hair:

* Thick and natural hair: 60 to 90 minutes
* Curly and dark dyed hair: 50 to 60 minutes
* Fine and lightly coloured hair: 40 minutes

Rinse with water to remove 100% of the product from the hair. Avoid contact with eyes during rinsing.

Dry hair 100% using a hair dryer.

Taking very fine sections, apply flat iron 12 - 15 times from roots to tips. Make sure sections are thin (you should be able to see you finger through your hair) and use a temperature of 180°C to 210°C (375°F to 410°F).

For longer lasting results we highly recommend using Protein Home Care Kit by Let Me Be - Shampoo, Conditioner and Mask.

Especially on your first wash it is important to use Protein Home Care Mask.

Use a blow dryer to dry your hair after every wash.

Its nourishing blend includes Amla, Argan, Jojoba, Macadamia, Coconut, Avocado, Silk Protein, Vitamin E, Panthenol, Shea Butter, and Mango Butter. These ingredients work together to provide nutrition, replace proteins, reduce porosity, align hair strands, and seal the cuticles. The outcome is straight, hydrated, soft, and easy-to-manage hair. This product is free of parabens and minerals.

Do not expose to the sun or temperatures above 50ºC.

Keep out of reach of children. Avoid eye and skin contact.

In case of irritation due to eye or skin contact, wash thoroughly with running water.

Good for hair making it smooth

It helps my hair feel smooth but not straight enough after the first wash in 4 days after applications. My hair is smooth but the curl is still there. Its good though that it doesn't hurt my eyes and nose. It helps calm my hair and frizzy free but the curl is still there which I wanted to be gone as well even if for a while.

No more costly salon visits for me!!

this was so easy to apply and with a little help from my mum to do the back I was able to achieve a sleek look. Love the price and quality of this product!! I admit I didn't follow the instruction exact and just squirted it on my hair and used a comb to distribute it out, yet it still turned out amazing. The best part is that it doesn't have a chemical smell like other brands or have any burnt aromas.

Just a bit tricky if you want to do yourself, arms get so tired! But so much cheaper than the hairdressers, happy I've found an at home option and can save my money
