Why am I still finding nits after treatment?
There could be multiple reasons for finding nits even after treatment. One possibility is that the treatment was not 100% effective in eliminating all the lice and nits. It is important to follow the instructions carefully while applying the treatment and to use the recommended amount for the recommended time period.
If the treatment is not left on for the recommended amount of time, it may not completely eradicate all the nits and lice.
Another reason could be due to reinfestation. Lice can easily spread from person to person, so it is important to identify and treat all close contacts. Failure to do so can lead to reinfestation, which will require a repeat of the treatment. One should also thoroughly wash all bed linen, towels, and clothing in hot water after treatment to eliminate any remaining lice.
It is also possible to mistake shed nits for live nits. It takes around 1-2 weeks for the nits to hatch, and the empty shells remain attached to the hair strands. These nits can be mistaken for live ones, but they do not pose any risk of infestation. Hence, it is important to differentiate between live nits and empty shells.
Lastly, it is essential to be patient and persistent while treating lice infestations. Even if some nits are left behind after the initial treatment, continued combing and nitpicking can help in getting rid of them. It is also recommended to schedule a follow-up appointment with a healthcare provider to ensure all the lice and nits are eradicated completely.
finding nits even after treatment can occur due to various reasons, but ensuring proper treatment, identifying close contacts, washing linen, and being consistent with combing and nit-picking can help in eliminating all the nits and avoiding reinfestation.
Can I get rid of scabies without going to the doctor?
Scabies is a common skin condition caused by a tiny mite called Sarcoptes scabiei. It is usually characterized by intense itching, rashes, and small raised bumps on the skin. While it is always recommended to consult a doctor if you suspect you have scabies, there are some home remedies and over-the-counter treatments available that can help get rid of scabies.
However, it is worth noting that getting rid of scabies without the help of a doctor may not be an easy task. Scabies mites can lay eggs under the upper layer of the skin, and they can be very difficult to get rid of using only home remedies. Additionally, the symptoms of scabies can persist for a long time, even after the mites are eliminated, and this can be frustrating and uncomfortable.
That said, there are some things you can do to help eliminate scabies at home. Firstly, you should wash all your clothes, towels, and bed linen in hot water and dry them on high heat. This will help kill any scabies mites that may be hiding in your clothes and bedding. Secondly, you can apply a topical cream or lotion that contains permethrin, which is an effective treatment for scabies.
You can buy permethrin cream over the counter at most pharmacies, and it is generally safe to use. Be sure to follow the directions carefully and apply the cream to your entire body, from your neck down to your toes.
Another over-the-counter treatment option is the use of sulfur soap. This soap contains sulfur, which is a natural antifungal and antibacterial agent, and it can help kill scabies mites. However, sulfur soap can be harsh on the skin, so it is best to use it only on the affected areas of your body.
In addition to these treatments, there are some other things you can do to help soothe the itching and discomfort of scabies. You can take cool baths or apply cool compresses to your skin to help relieve the itching. You can also take over-the-counter antihistamines, such as Benadryl, to help reduce the itching.
While it is possible to get rid of scabies without going to the doctor, it is always recommended to seek medical advice if you are unsure about your condition or if your symptoms persist for more than a few days. A doctor can diagnose scabies more accurately, prescribe stronger medications if necessary, and provide additional advice on how to prevent the spread of scabies to others.
