It's no secret that some of the best natural hair products can be found in kitchen cupboards, but this latest revelation is a real surprise.
Although she was apprehensive at first, Ishika says applying the oil on her scalp at least twice a week has helped to improve the density and quality of her hair, with "new baby hairs popping up in no time".
She also claims this homemade product can be used to reduce grey hairs, as her grandma has noticed new black roots appearing.
Brave enough to give it a go? Here's how:
1. Mix one teaspoon of red chilli powder (don't use chilli flakes) with coconut or almond oil to form a paste.
2. Apply over the scalp by parting sections of the hair and pressing the oil into it. Don't rub it as this can irritate the scalp.
3. Let the oil soak in for at least half an hour.
4. Rinse with your regular shampoo - and don't be alarmed if you experience a tingling sensation. This is the blood rushing to your scalp, says Ishika.
So, what do the experts say about using this treatment at home? Dermatologist Sejal K. Shah, M.D. spoke to Huffington Post Style to explain how the capsaicin found in chillis has anti-inflammatory and antioxidant benefits. It can also increase blood flow, which is needed for a healthy scalp.
However, Dr Shah warned that chilli oil can cause irritation and swelling, especially if it gets in the eyes.
"If there is worsening of the scalp or hair loss, the treatment should be stopped immediately," she said. "If you are considering any alternative treatment, you should discuss it with your doctor before proceeding."
