My Experience With Doo Gro Mega Thick Growth Oil

I was fed up with my thinning hair in January 2025, noticing more strands in my brush every morning. My scalp felt dry, and I knew I needed a boost beyond my usual shampoo.

I grabbed Doo Gro Mega Thick Growth Oil on February 1 for $12.99 at a local store. The 4.5-ounce bottle promised thicker, stronger hair with ingredients like biotin, castor oil, and vitamin E.

I started with a few drops, massaging it into my scalp after a shower. The light herbal scent was a nice touch, and it absorbed quickly without greasiness.

By February 15, my scalp felt less itchy, and new growth peeked through. I was thrilled to see tiny hairs along my hairline.

March 10 brought rain, and I used it nightly, noticing less breakage. My hair felt softer, even in the damp weather.

On April 5, I added it to my ends during a heat styling session. It protected against split ends, a win for my curly locks.

May 20’s 90°F heatwave tested it, and I applied it sparingly to avoid oil overload. My hair stayed manageable, though I stored it in a cool spot.

June 12’s cold snap at 20°F had me indoors, and it kept my scalp hydrated. I loved how it worked with my winter hat.

July 1 marked five months, and I’d gone through two bottles. Thickness improved, especially around my crown.

August 5’s humidity made my hair frizzy, but the oil tamed it with a light application. I’ve tracked its effects daily, noting growth and texture.

Now, at 12:55 AM +06 on August 18, 2025, I’ve tweaked my routine for seasons. I’m excited to share this with you—let’s get your hair thriving!
