use with other colors

I have other Henna shade but it doesn't cover gray well. So I mixed them with black to allow a better coverage of gray. So, it is trial and error to see how much black to add, too much, the browns doesn't show, too little, the gray doesn't get covered. But overall it works!

First time usage of Black henna hair colour

Tried this chemical-free henna hair colour once and happy so far. It has been a week plus and the colour still last. No itchiness or hair fall so far. Hair felt a bit dry since shampoo can’t be used right after, but it was fine after washing on day two. Other than that, appreciate if the cover lid is sealed to avoid any spillage. It’s a great chemical-free option! Advisable to read the instructions on their official website for more details.

Ilike that this product comes with natural ingredients. It doesn't irritate the hair or the scalp. The colour lasts for a long time. The packaging of the product is convenient and easy to use. The colour of the product comes out great on the hair after it's been applied. The scent is not too strong.

Great

The henna has a rich, earthy aroma and a fine texture that mixes smoothly into paste. It stains beautifully, leaving a deep, natural color that lasts well and fades gracefully. I appreciate its purity—no harsh additives—and the way it nourishes hair and skin while offering vibrant results. A timeless, natural product that feels both artistic and restorative.

Great henna!

My first time trying out this henna. The size is just nice and I’m sure it can last a long time. It is powdery so make sure you use gloves so you won’t stain your hands. I used my own conditioner after shampooing so it leaves my hair soft.

My hair has been growing

I use henna with other powders to infuse my oils and treat my scalp to promote hair growth and restore my edges. It has helped in moisturizing my scalp without any side effect for my very sensitive scalp. Another benefit is that it seems to have slowed down my hair turning gray. Therefore, I will buy again, but the size is so convenient that, despite continued use, I won't be needing to make another purchase until next year.
