Step 1. Start with a clean scalp, meaning no product-build up like dry shampoo. It's okay if your scalp has natural oils.

Step 2. Apply the oil directly on the scalp and gently rub the solution into your scalp for 3 to 5 minutes for better absorption (divide your hair into sections for more efficient application).

Step 3. Cover your hair with plastic wrap to prevent the oils from drying out and attracting dust/pollution. To secure the wrap, tie a scarf or wear a bonnet.

Step 4. Keep the oil on for at least 4 hours to do its magic, or you can even leave it on overnight.

Step 5. Wash your hair as you usually would. (to make sure the oil is completely rinsed out, try using a coffee rinse before you shampoo.

I Finally Feel Hopeful Again

I've struggled with thinning hair for years, and nothing ever really worked. But after using the Afsennah scalp treatment, I actually see new growth. My scalp doesn't feel itchy or dry anymore either. It's been such a relief.

''I’ve been dealing with hair loss for years and tried so many things without real results. Then one day, I came across Afsennah on Instagram it honestly sounded too good to be true, but I gave it a shot. Not only has my hair shedding slowed down, but I’m finally seeing new growth in my thinning areas and even my bangs are filling in. If you’re struggling like I was, this is truly worth trying''

Sally T.

''After having my third baby, I started losing so much hair I genuinely thought I was going bald. I came across Afsennah and decided to try their custom routine based on my hair needs. I used the recommended scalp treatment and hair treatment consistently for 3 months (even with a few missed days), and by month 3, the difference was unbelievable. I didn’t notice much at first, but when I looked at my before-and-after photos, I was honestly shocked. This is the only thing that’s truly worked for me it feels like a miracle''

'' I experienced severe hair loss over 60% of my hair fell out and the texture completely changed. A friend of mine mentioned she was seeing amazing results using Afsennah, so I decided to give their custom routine a try. Within a few weeks, my hair started to feel healthier, and I noticed new growth coming in. After two months, the improvement was undeniable. Afsennah truly works! PS: I also got COVID which also caused a lot of hair loss''
