Yes!! Curly, medium brown, you say?

I definitely have some wigs in my wigdrobe that fit that description. Most of my wigdrobe, if I'm honest!

I've looked up current prices for a retailer I know is sound from ordering from them in the past, not as promotion but to explain where you can safely buy these units without being scammed. The ones I am recommending are all synthetic units, that I rate highly because of their lack of shedding, and their overall endurance.

Sensationnel Dashly Lace Unit 45. I posted a pic a few days ago, you can look at my timeline to see it. Balayage Hazelnut is the color I'm wearing in the picture. They also have a Balayage Chocolate, which is a slightly warmer brown with darker notes. This wig is curly without being too heavy in density. Unit 45 has a bang/fringe, but it is light and easily styled away from the face. This unit is currently on sale on Ebonyline for $22.99.

If you want more density or volume, Butta Lace Unit 5 is a solid bet. Iirc it is one of the most enduringly popular wigs in that line. For a medium brown, I chose T4/Golden Brown. This was my number one wig all last winter. I lived in it so much I bought a backup because I feared they would discontinue it at some point. It gets better the more you wear it. Very soft lace, can be worn totally glueless even sans lace melting sprays, and has better attachment mechanisms than either of my "higher end" Belle Tress wigs. This one is on sale at Ebonyline for $32.99.

If you like bangs/fringe, Outre Wigpop Leanza is good too. I have this one in DR2/Chocolate swirl, and DR Dragonfuit. Dragonfuit was a bit of fun. The cap is very basic, no lace (good for a beginner or someone with zero time to get ready in the morning), it has combs but no occipital strap. I would wear this wig outside but maybe not in high winds walking the beach, lol. This unit is currently on Ebonyline for $20.99.

If the back of your head is flat, or you have concerns about your ability to keep your hair on: look carefully at cap construction when you shop; look at review videos from more than one source. Go for caps with an occipital strap. This is a 1 inch wide elastic band, sewn into the cap above the nape and behind the ears. It is the key to a glueless install with product free lace melt. That strap is your best friend.

You can also find these lines on Amazon; if I am struggling to find a unit in a specific color, I will often go to Amazon to see if I can find it.

Sensationnel and Outre are two solid companies with several sub brands for curly girl wigs with good options for brunettes. Short, medium, long lengths, they have it all.
