Red or Black Toenail Picture & Photo Gallery:
Look:
- A red toenail generally means fresh blood or a fresh injury.
- This can be called a toenail hematoma or fresh blood from repetitive irritation.
- A black toenail is generally more dried blood that has crested underneath the toenail.
- Very infrequently, can a black toenail be something more dangerous like melanoma?
- It is also possible for your toenail to the infected with toenail fungus. This can also then result in rubbing and bleeding after the toenail fungus.
- If there is toenail fungus, this is usually more of a brown or yellow color.
- A toenail falling off is a widespread problem as well.

Black Streaks under the nails overview:
Black Streaks under the nails (fingernails or the toenails) can be very dangerous. Follow our diagnosis guide to see if you should be worried!
Note: None of the photo galleries shows any true melanoma or cancerous growth. This is because it is that rare that we don’t actually have any photos of it!
Causes:
- The most common cause of black under the toenails is dry blood.
- Most People Should Not Be Worried!
- A thick black dark streak could be a subungual melanoma- a type of skin cancer.
- Don’t be too worried, though. The odds are low that you actually have this tough but better safe than sorry!
- Watch the video above to get a better idea if this is what you have.
- But always make sure to get checked out.
Dangerous Cause:
- Subungual melanoma is the most dangerous cause.
- It is a rare form of skin cancer; it is usually seen between ages forty and seventy.
- It is not due to sun exposure or trauma.
- It just appears one day without any incident.
- If your dark spot appears after an injury, then you are most likely on the safe side.
Subungual Melanoma:
- The outlook is usually excellent if the cancer is confined to just the toe.
- Most people that suffer from this disease have avoided seeking treatment for many, many years. It has usually spread far throughout the body.
- If you are cautious and follow up on the streaking and ulcerating in a reasonable amount of time, you will most likely be safe.
- The cure consists of excising the lesion or amputating the tip of your fingernail.
- See your podiatrist as soon as possible!
Visit a podiatrist for a biopsy immediately if:
- The black streak is over 3 millimeters in width.
- The streak is widest at the start of the nail origin.
- The streak is not uniform or appears disrupted.
- The streak changes color the further you get.
- The streak continues from under the nail into the skin, termed “Hutchinson’s sign.”
- The nail becomes deformed, bloody, or starts to crack in the area of the streak.
- The nail looks very unusual compared to the other nails.
- The streak is more common in the thumb and the big toe.
- In this case, the streak may even be white; in this case, be aware of a nodule or irregularity forming under the nail plate.
- If you have ever considered that there may be a wart underneath your nail that is just not healing.
Safe Causes:
- The odds of the streak in your fingernail are actually pretty low because many people, especially African Americans, normally have light, thin streaks of dark pigment that form a vertical line down their nail, which is completely normal. It is effortless to predict whether the streak is dangerous or safe.
- Normal vertical streaks of pigment that are not melanoma. This is especially common in non-white individuals. These are usually thin lines in a very normal-looking nail; check the guide below to see if you are on the safe side or if you should get it checked out.
- Trauma and loss of fingernail leading to a streak of blood. If the blood is not advancing, then you should get it checked out to be safe! But this should eventually grow out at 1mm per month.
Probably safe if:
- The streak is less than 3 millimeters in width.
- The streak is uniform in length and of continuous color as it progresses down the nail.
- The streak or pigment is only present in the nail and not in the skin.
- The nail is not deformed, bloody, or cracked in that area.
- The nail looks normal compared to the other nails.
Other Causes Of Black Spots Under The Toenail:
- Blood under the toenail. Other causes include:
- Pseudomonas nail infections
Toenail Fungus Can Cause Black Streaks:
If the above does not sound like your situation, consider toenail fungus as well.
- Toenail fungus is associated with 80% of all toenail problems.
- It usually manifests as thick yellow toenails, but there can be brown and black marks as well.
Toenail Fungus Is Associated With 80%+ Of All Toenail Problems:
Symptoms of Toenail Fungus:

How to fix toenail fungus:
- There are many different types of toenail damage.
- In our experience, about 90% or more is related to toenail fungus.
- The key to toenail fungus is to trim it as much as possible and file that nailed down.
- If you can do that, you have to make sure you can kill fungus the rest of the way.
- The best way to do that is to soak exfoliate the affected toenail skin. So, consider foot soaks.
- At the same time, you have to apply antifungal medication such as these medications recommended here or the toenail repair pens.

Best Shoes For Toenail Injuries:
- The key to prevent toenail ripping and lifting is to have a good supportive pair of shoes.
- If you have a good supportive shoe that keeps pressure off your toes in your toenails, there will be no lifting and cracking to allow bacteria and fungus to get in.
- This almost seems counter-intuitive, but when people make a switch to perfect supportive shoes that fit properly, their toenail problems almost always get better over the next few months or a year.
- Your current nail is already likely destroyed, especially with joggers toe, but let the new nail growing healthy without new damage.
- Click the following link for our most recommended shoes. Try to focus on shoes with mesh and room around the big toe and also the smaller toes.
Good Luck with the Black Streaks Under the Nails!
Get The Best Shoe Fit:
- One of the most common biomechanical causes of toenail problems, bunions, hammertoes, and outside of the foot problems is poorly fitting shoes.

- If you have too small or too big shoes, this can result in crowding or too much motion and sliding within your shoe.
- This can cause people to walk improperly and put more weight on their knees, hips, and lower back!
- We usually find that people make some of the 10 mistakes that we talk about.
